Diagnosing Odor in Cats

Skin odor is a common manifestation of a skin infection. The most common skin infections in cats are bacterial (superficial pyoderma) and yeast (Malassezia dermatitis) infections. Skin discharge and/or odor can indicate that your cat may be suffering from a skin infection.

What are bacterial and yeast infections?

Bacterial infections are usually caused by bacteria that are part of the normal flora of the skin (e.g. Staphylococcus intermedius). For this reason, the infection is not contagious to other animals. In cats that have abnormal skin (e.g. allergies) the bacteria increases in number and causes red bumps (papules) and rancid odor. Some cats with bacterial skin infections also develop excessive shedding, patchy hair loss, and scaling. If the infection is left untreated, it may reach deeper parts of the skin. In these cases, nodules that have a purulent (pus) discharge develop. In most cases skin infections are secondary, so it is very important to pursue an underlying cause. Failure to do so will result in reoccurring infections.

Animals often develop a yeast infection (Malassezia dermatitis), which manifests itself as greasy, red, itchy skin with a rancid odor. Areas most commonly affected include the ventral neck, groin, armpits (axillae), and perineal areas. This infection is also secondary to an underlying disease, most commonly allergies. In some cats this may be a consequence of chronic antibiotic and steroid therapy but, as a general rule, cats do not develop yeast infections after antibiotic therapy as commonly as people do.

Diagnosis of Skin Discharge or Odor in Cats

• History is very important for the proper diagnosis of skin diseases. Your veterinarian will ask questions regarding the age of onset, progression of the disease, and response to previous treatments.

• Skin cytology provides useful information on the type and severity of infection. Your veterinarian may take samples of skin (e.g. swabs or tape impressions).

• In some cases, a biopsy may be necessary to establish a final diagnosis. Some samples may be used for cultures of various types while others may be sent to a pathologist to obtain more information about the cells that are present in the skin.

Treatment for Bacterial Dermatitis

Treatment for bacterial skin disorders is antibiotics. Some of the more commonly used antibiotics include ampicillin, cephalexin, enrofloxacin, clindamycin, clavulinc acid and sulf based drugs.

The minimum length of therapy for superficial pyoderma is 3 to 4 weeks. The minimum length of therapy for deep pyoderma is 8 weeks. As a rule, therapy should be continued for 2 to 4 weeks beyond the resolution of clinical signs.

Treatment of Malassezia Dermatitis​

Systemic therapy is reserved for severe cases. It is important to note that griseofulvin is not effective against yeasts. Ketoconazole, itraconazole and fluconazole are all effective against Malassezia.

Topical therapy as the sole treatment is only effective in mild cases while severe cases usually require systemic therapy. Selenium sulfide (Selsun Blue®) is a keratolytic, anti-seborrheic, degreasing agent that will kill Malassezia (effective in 65 percent of cases).

Ketoconazole shampoo (Nizoral®) is approved in many countries for the treatment of seborrheic dermatitis in people and is usually effective in killing Malassezia.

Chlorexidine at 2 to 4 percent might be effective against yeasts, 0.5 to 1 percent is not effective.

Miconazole (Dermazole ®, Resi-zole® leave on conditioner) is also effective.

Vinegar/water rinse (1/5 to 1/10) is a cheap and effective long-term maintenance treatment to prevent relapses.

At-Home Care for Cats

You will need to shampoo your cat with medicated shampoos. Benzoyl Peroxide is an excellent antibacterial antibiotic (e.g. Oxydex®, Pyoben® shampoo). Other antifungal shampoos contain miconazole or ketoconazole (e.g. Nizoral® shampoo for dandruff is now available OTC).

Contact time is important when using a medicated shampoo. You should allow a 10 to 15 minutes contact time for the product to be effective. Leave-on products are also available on the market for prolonged efficacy.

You may have to administer oral medications (either antibiotics or antifungal medications) to help treat the infection. Compliance is very important. Some cats may require medications for a prolonged time as skin infections usually take a while to clear. Speak with your veterinarian before administering medication to your pet.

If your cat keeps relapsing with infections, it is important to pursue an underlying cause. This will decrease the frequency of relapses and reduce the risk of resistance to medications used for prolonged periods of time.

Preparing Your Pet for the 4th of July + Fireworks

It’s almost July and you know what that means: barbeques, open doors, fireworks, and scared pets. This time of year can be especially frightening for our furry friends. In our experience, July 4th is the busiest holiday for lost pets in the whole year. Here are some ways that you can prepare your pets and keep them safe and calm before and during the celebrations:

• Take your dog out for plenty of exercise during the day before the festivities begin

• Keep pets indoors. They may feel safer if they are placed in a smaller interior room with a radio/tv playing.

• Close your windows. Dogs in particular can try and get out of the house by pushing out the screen. Dogs have been known to bolt through screen doors, so keep your inside door closed.

• Check your fence line for loose boards or openings that your dog could slip through or dig out of. We suggest you even keep a leash on your dog and walk them in the fenced yard during peak fireworks times. Never leave your pet unattended, even in a secure yard.

• Have current, clear photos of your pets on hand. If they do go missing, you will want to be able to quickly create flyers to distribute in your neighborhood.

• Make sure all your pets' microchips are registered and your contact information is up-to-date in your pet's microchip account, and that they are wearing visible ID such as collars and tags that display their name and microchip number clearly.

• If you have outdoor cats, make sure they are inside before nightfall during this season.

• Provide a safe space for pets to retreat such as a closed room with their favorite toys, blankets, pillows, and plenty of water.

REMEMBER: if your pet gets scared by the fireworks and escapes from your property, don’t panic! They are generally running away to find a hiding spot away from the loud noises and flashing lights. Do not chase or whistle for the animal, as it may make them more distressed. Alert local authorities, animal shelters, and put in a Lost Pet Report with your local Facebook and Neighborhood groups.

Trimming a cat's claws

Trimming a cat's claws every few weeks is an important part of maintaining your pet's health. Not only does a quick trim protect you, your pet, and your family, it can also save your sofa, curtains, and other furniture. Nail-trimming is also a fast and effective alternative to declawing, which involves surgical amputation and can cause behavioral and health issues.

If the idea of trimming a cat's claws has you biting your nails, know that all it takes is some patience and a bit of practice to sharpen your skills.

Staying on the cutting edge

There are plenty of tools available to trim a cat's claws; use the one that works best for you and your pet.

Some people prefer a special pair of scissors modified to hold a cat's claw in place, others prefer human nail clippers and still others choose plier-like clippers or those with a sliding "guillotine" blade. Whatever your tool, be sure the blade remains sharp; the blunt pressure from dull blades may hurt an animal and cause a nail to split or bleed. Keep something on hand to stop bleeding, such as styptic powder, cornstarch, or a dry bar of soap (to rub the bleeding nail across).

Take paws

If you approach a cat with a sharp object in one hand while trying to grab a paw with the other, odds are you'll come up empty-handed. Because cats' temperaments and dispositions vary greatly, there is no "perfect" way to handle a cat while trimming their claws

Some cats do well with no restraint at all, but most cats need to be held firmly but gently to make sure that no one gets hurt. Try resting the cat in the crook of one arm while holding one paw with the other hand. Or, place the animal on a table and lift one paw at a time. You may even be able to convince a particularly sociable cat to lie back in your lap. If you've got a helper, now’s their time to shine: ask them to hold the cat while you clip the nails, or just ask them to scratch your cat's favorite spot or offer up a distracting treat.

Alternatively, you may try to gently restrain your cat with a towel or blanket using the 5-step "scarf wrap" method.

Taking a little off the top

Now that you're in position and the cat's in position, put the claw in the right position, too. Take a paw in your hand and use your thumb and pointer finger to gently press down on the top and bottom of the paw on the joint just behind the claw. This will cause the claw to extend so you can quickly but carefully snip off the sharp tip and no more.

Don't get too close to the pink part of the nail called "the quick," where blood vessels and nerve endings lie. Just like the pink part of a human fingernail, the quick is very sensitive; cutting into this area will likely cause bleeding and pain.

If this happens, apply a little pressure to the very tip of the claw (without squeezing the entire paw, which would only increase the blood flow), dip the claw in a bit of styptic powder or cornstarch or rub the nail across a dry bar of soap. Don't continue if they’re too upset, but keep an eye on them to make sure the bleeding stops.

It's common to only cut the front claws, but take a look at the rear claws just in case they've gotten too long, especially if their sharp tips hurt you when your cat leaps on or off your lap. Since most cats fuss more about having their rear claws clipped, start with the front claws.

One at a time

If you aren't able to trim all 10 nails at once, don't worry. Few cats remain patient for more than a few minutes, so take what you can get, praise your pet for cooperating, then be on the lookout for the next opportunity—maybe even a catnap—to cut things down to size.

Cannabis (Marijuana) Intoxication in Cats and Dogs

Marijuana (or cannabis) refers to the dried parts of the Cannabis plant. Cannabis has been used since 500 BC as cannabisan herbal medicine, and for products such as rope, textiles, and paper. Today, cannabis is primarily used for medicinal or recreational purposes. Cannabis can be smoked like a cigarette, inhaled via vaporizers, or ingested via food and drink.

Cannabis contains more than 100 different chemicals (or compounds) called cannabinoids. Tetrahydrocannabinol (THC) is the cannabinoid that has the most psychoactive effects. It is also the compound responsible for some of cannabis’ medicinal uses, such as treating nausea and improving appetite in cancer patients. Other compounds, such as cannabidiol (CBD), have shown promise for medicinal use and do not have psychoactive effects.

"The increased accessibility to the drug has led to an increase in accidental exposure in pets."

While cannabis use is not new, its use for recreational purposes is more recent. In the 1970s, cannabis was criminalized in the US when it was labeled a Schedule 1 (Class I) drug. In the 1990s, individual states began legalizing cannabis for medicinal use, and more recently, 9 states have legalized it for recreational use. Legalization for recreational use in Canada occurred in 2018. As with any other medication, the increased accessibility to the drug has led to an increase in accidental exposure in pets.

How do cats and dogs become intoxicated?

Cats and dogs can become intoxicated by cannabis in various ways; by inhaling second-hand smoke, eating edibles (baked goods, candies, chocolate bars, and chips containing cannabis), or ingesting cannabis directly (in any form). Most exposures are accidental when curious pets discover access to the drug or when they are present in the same room with a person smoking cannabis. Dogs have more cannabinoid receptors in their brains, which means the effects of cannabis are more dramatic and potentially more toxic when compared to humans. A small amount of cannabis is all it takes to cause toxicity in cats and dogs.

Regardless of the method of exposure, accurate and complete information is imperative to treat the patient successfully. For example, ingestion of a 'pot brownie’ needs different treatment than inhalation, because eating the brownie requires treatment for cannabis and chocolate toxicity, whereas inhalation may require additional treatment for respiratory irritation.

How does cannabis affect cats and dogs?

Like most drugs, the effects of cannabis are based on chemistry. The drug enters the body via inhalation or ingestion and binds with specific neuroreceptors in the brain, altering normal neurotransmitter function. THC interacts with neurotransmitters such as norepinephrine, dopamine, serotonin, and acetylcholine. Humans and pets have two types of receptors in their bodies. One type, CB1, affects the central nervous system, and the other, CB2, affects the peripheral tissues. Although not all the pharmacologic mechanisms triggered by cannabinoids have been identified, it is thought that CB1 is responsible for most of the effects of cannabis.

Everything that enters the body has to exit the body. THC is very lipid-soluble, which means that it is easily stored in the fatty tissue in the liver, brain, and kidneys before being eliminated from the body. THC is metabolized in the liver and the majority (65-90%) is excreted in the feces, while a small percentage (10-35%) is eliminated through the kidneys. The drug has to be metabolized and excreted for the effects to wear off.

How toxic is cannabis?

Cannabis is considered to have a high margin of safety for people; however, not all people, and certainly not all pets follow a single pattern of intoxication. A small amount may affect one pet more than another, so there is no official safe level of exposure. Differences in age, health status, and body size are some of the factors that can lead to toxicity differences.

Luckily, cannabis intoxication is seldom fatal. The average marijuana cigarette contains about 150 mg of THC. The minimum lethal oral dose of THC in pets is fairly high; however, deaths have been noted after ingestion of foods containing highly concentrated cannabis, such as medical-grade THC. In fact, fatalities were very rare until the development of medical-grade products.

What are the signs of cannabis intoxication?

Many of the signs of intoxication are neurological. Pets may become wobbly and uncoordinated. They may be hyperactive, disoriented, and very vocal. Their pupils may dilate, giving them a wild-eyed appearance, and they may drool excessively or vomit. They may also develop urinary incontinence (i.e., urine leakage). In severe cases, tremors, seizures, and coma can result.

Side effects are usually short-lived, but they can still be dangerous. Physical signs include low or elevated heart rate and blood pressure and slowed respiration rate (breathing rate). Lethargy and increases or decreases in body temperature may also be observed. Fortunately, these side effects are usually short-lived, but they can still be dangerous and make the pet quite miserable.

How is intoxication diagnosed?

Diagnosis is based on an accurate history and clinical signs. Although there are tests to determine the level of THC in the urine, the results take time, making them impractical. Human urine drug-screening tests are quicker but are not dependable in pets. The diagnosis is made much more quickly and treatment initiated when responsible pet owners provide accurate information regarding the pet's exposure.

How is intoxication treated?

When a toxin enters the body, often the first line of defense is to get it out. If the toxicity is discovered shortly after ingestion, your veterinarian may induce vomiting to prevent further absorption of the toxin. Two factors may interfere with this early defensive strategy. First, the signs of toxicity may manifest only after the drug has been absorbed, meaning it is already in the system. Second, cannabis has an anti-emetic effect that inhibits vomiting. In life-threatening cases, the stomach may be pumped (gastric lavage). Activated charcoal may be administered every 6-8 hours to neutralize the toxin. Enemas are also used to reduce toxin absorption from the GI tract.

The second line of defense in cannabis toxicity involves providing supportive care until the effects of the drug wear off. Medications and supportive care to regulate the pet's heart rate, respiration, and body temperature are used if needed. Since the pet may be lethargic, with no desire to eat or drink, IV fluids can help prevent dehydration, support blood pressure, and maintain organ function. Anti-anxiety medications can minimize agitation. To prevent self-trauma while the pet is disoriented and uncoordinated, confine them in a safe, comfortable space. Noise should be kept to a minimum to decrease sensory stimulation.

The Bottom Line

The bottom line, when it comes to cannabis use and pets, is similar to that with other drugs in the home: Be careful. Keep all forms of cannabis, medical or recreational, out of reach of your pet. Consider storage in high cabinets or in locked drawers when not in use. Keep pets in a separate and well-ventilated room, away from second-hand smoke. Remember that pets have a good sense of smell and will be tempted to eat candies, chips, chocolates, and cannabis directly if accessible. If you notice suspicious behavior in your cat or dog and cannabis exposure is a possibility, take your pet to your veterinarian or the nearest emergency veterinary hospital for treatment.

Spring Weather Plays Havoc on a Cat's Hormonal System

Spring is right around the corner and with it brings an important consideration for your cat.

With spring comes longer days. The sun comes up earlier and stays up longer. And this increasing day length plays with a cat's hormones. The result is kittens; lots and lots of kittens.

Of course, kittens are cute and cuddly. Everybody loves kittens. But kittens grow up to be adult cats pretty quickly. Before long, kittens start making kittens of their own.

A female kitten can come into heat and become pregnant as early as 5-6 months of age. Male kittens generally become fertile about the same time as well. In addition, an intact female cat can become pregnant with a new litter while she is still nursing and caring for her previous litter. She can have several litters in the course of a year.

All in all, the reproductive cycle of the cat makes the species a pretty efficient breeding machine. That’s one of the reasons why spaying or neutering cats are so important. Spaying/neutering is the only effective way to control the cat population. So if you haven’t had your cat spayed or neutered yet, it’s time to think about getting that done.

Of course, there are other reasons also. Spayed or neutered cats make much better pets than those that are unaltered. Female cats are very vocal when they are in heat. Those that have considered breeding their female cats have changed their minds for this very reason. Living with a cat that is in heat is not a pleasant experience. (Not to mention the fact that breeding your cat solely for the purpose of making kittens without a well-planned breeding program in place is not a responsible action.)

The same can be said of male cats. Unaltered males have strong-smelling urine and can develop undesirable habits like urine spraying on everything and anything. Though spraying behavior can occur in altered males as well as in female cats, neutering your male cat definitely reduces the possibility of this behavior occurring.

There are also health benefits for altered cats. Female cats spayed prior to their first heat cycle have a significantly lower risk of mammary cancer later in life. The risk of a severe uterine infection known as pyometra is removed completely when your cat is spayed.

Remember also that your unspayed female cat can become pregnant if she lives in a household with an unaltered male, even if the male is related to her.
