Feline Distemper (or Feline Panleukopenia Virus)

What is Feline Distemper / FPV in Cats?

FPV / Feline Panleukopenia Virus, otherwise known as Feline Distemper, is a highly contagious, life-threatening infectious disease in cats. It mostly affects kittens and unvaccinated cats, and it can be fatal if not appropriately diagnosed and treated. It is closely related to canine parvovirus (often confused as it is not related to the canine distemper virus).

The feline panleukopenia virus infects and kills the rapidly growing and dividing cells in the body, including cells in the bone marrow, intestines, and skin, and in a developing fetus.

The virus suppresses the production of all white blood cells in the bone marrow. These cells are important to the immune system and are used to fight infection. Without them, the cat is vulnerable to spreading the virus.

Infected cells in the intestines eventually lead to diarrhea, decreased appetite and vomiting. Severe dehydration ensues and the safety barrier between the intestines and the rest of the body breaks down, leading to secondary bacterial infections. The virus spreads quickly and is fatal, if left untreated.

Feline distemper virus is found everywhere in the environment; it is strong and can live for years. The virus can survive in the environment it was shed into or be carried on shoes, paws, bedding, bowls, litter boxes, etc. It can survive at freezing temperatures and room temperatures, and it can also survive the use of certain disinfectants, including iodine and alcohol.

The virus enters the body through the nose or mouth; the specific cat’s immune system determines the number of viral particles that enter the body. Usually, the virus invades the bone marrow and intestines within two to seven days of the cat coming into contact with the virus.

Panleukopenia is considered one of the deadliest cat diseases in the unvaccinated cat population. Kittens, cats with depressed immune systems and pregnant cats are at the highest risk to develop severe clinical signs of this disease.

Symptoms of Feline Distemper / FPV

Symptoms of feline distemper can range from mild to severe and may include the following:

• Lethargy

• Depression

• Vomiting

• Diarrhea

• Painful abdomen (when touched or may appear tense and distended without touching)

• Dehydration

• Weight loss

• Rough or unkempt hair coat

• Fever

• Decreased to absent appetite

• Collapse (in severe cases)

• Bruising of the skin or gums (in severe cases)

Kittens infected in the womb during the late stages of pregnancy may develop cerebellar hypoplasia once born, a condition where the virus affects the formation of a part of the brain called the cerebellum. This is the part that coordinates balance and movement.

Affected kittens will have mild to severe intention tremors and a wide-based stance. They may fall frequently or seem uncoordinated. Luckily, this is not considered a painful condition, and these special-need kittens, if kept in safe environments, can live long happy lives.

Causes of Feline Distemper / FPV

Cats become infected with this virus in utero due to their mother becoming infected while pregnant or being exposed to it in their environment. Kittens can also be infected in utero or via breast milk when feeding from their mother.

A cat carrying feline distemper virus will shed viral particles into the environment through feces, urine, saliva and vomit. Infection occurs when susceptible cats are in contact with these secretions.

Luckily, an infected cat only sheds the virus for a day or two, but since the virus is very stable in the environment, it can live for years. That is why it is common for cats to become infected due to their environment.

Diagnosing Feline Distemper / FPV

Feline panleukopenia can look like many other conditions, such as feline leukemia or feline immunodeficiency virus. Any kitten showing signs of fever, vomiting, diarrhea, depression, and a decreased appetite is a feline panleukopenia suspect. A thorough medical history can be helpful with diagnosis, especially if your cat was recently adopted, has been outdoors frequently, is unvaccinated, and/or has been around other cats.

Your veterinarian will likely do bloodwork to help with the diagnosis. Feline panleukopenia is suspected when exposure history is correlated with very low white blood cells and possibly low red blood cells (anemia).

Fecal testing for feline panleukopenia virus can be performed . If the cat received a panleukopenia vaccine 5-12 days prior to testing, this form of test is often falsely positive. Virus isolation (a test to find the virus in different tissue samples), antibody levels and PCR testing are also available to help confirm suspicions of feline panleukopenia.

Treatment of Feline Distemper / FPV

There is no specific treatment for feline panleukopenia. Dehydration is treated with aggressive intravenous fluid therapy while clinical signs of vomiting and diarrhea are treated with prescription medications.

Antibiotic therapy is often instituted to help control any secondary bacterial infections due to low white blood cell counts. However, antibiotics are not used to treat and clear the actual virus. For kittens and cats who appear in shock, or with severe infections, aggressive therapy and nursing care is necessary for resuscitation, using plasma/blood transfusions and anti-coagulant therapies.

Luckily, cats who do receive and respond well to aggressive therapy during the first few days of feline panleukopenia tend to have a good prognosis for a complete recovery. Kittens infected in utero during the early to middle stages of pregnancy typically do not survive. Those infected in the later stages of pregnancy tend to develop cerebellar hypoplasia but can live happy lives with normal survival times, depending on the severity of the neurological signs.

Prognosis decreases for cats with low protein levels, low temperatures, thin body conditions, and/or severely low white blood cells on bloodwork. These extremely ill cats have a poor prognosis and, on average, will pass away within 12-24 hours.

If a cat recovers from feline panleukopenia, there is usually no permanent damage to their organs, and they develop lifelong immunity to the virus.

Flatulence in Dogs

Flatulence occurs when gas builds up in your dog’s intestinal tract and colon. This is commonly caused by the dog eating something new – either a change in diet, or a food that they weren’t meant to eat. If your dog is eating food they can’t digest like dairy, soybeans, peas, or foods high in fat, they can experience chronic flatulence. Dog farts are typically not concerning, but if your dog’s gas becomes unbearable it may be time to make a change.

What Are Some Causes of Flatulence in Dogs?

Hard-to-digest foods like table scraps or spicy foods can give your dog an upset stomach, which can result in excessive gas or excessively smelly gas. Feeding them food or snacks with low-quality ingredients, fillers, or artificial preservatives can also give your dog gas.

If your dog is fed a high-quality diet and still has excessive gas, your veterinarian can test to see if they have poor digestion. They can also try to identify an intolerance or allergy your dog may have by eliminating ingredients from their diet and reintroducing them again.

Dogs who eat quickly will swallow more air while eating, which also leads to more flatulence.

Which Dogs Are Most at Risk?

If your dog is overweight, obese, or sedentary they are at a higher risk for chronic flatulence, regardless of diet. Short-nosed breeds like Pugs, Boston Terriers, Shih Tzus, and Lhasa Apsos tend to swallow a lot of air when they eat or drink, which causes excessive farting.

Could Flatulence Be a Symptom of Another Health Issue?

Once you’ve ruled out a food intolerance or digestive issue as the cause of your dog’s flatulence, you may need to visit your vet to identify a more serious cause. Persistent dog farts may be a side effect of the following health issues:

• Inflammation of the large intestine or colon (canine colitis)

• Irritable bowel syndrome (IBS)

• Stomach infection

• Intestinal parasites such as worms

• Inflammatory bowel disease

• Inflammation of the pancreas

• Cancer

What Can I Do to Reduce My Dog’s Flatulence?

A healthy and consistent diet is the best way to reduce your dog’s farts.

You can also try the following:

• Don’t give your dog table scraps. Dogs can’t easily digest scraps, including foods high in fats and sugars, which can cause bloating and discomfort.

• Don’t give your dog dairy products. Most dogs are lactose intolerant, which means that milk, cream, or cheese can upset their stomachs.

• Keep your dog out of the trash in your home and outside. Practice the command “leave it” when taking your curious dog on walks.

• Avoid giving your dog fart-inducing foods. Steamed vegetables like broccoli, cauliflower, and Brussels sprouts can be healthy for your dog, but also produce more gas.

• Slow down your speed-eater. Divide your dog’s food into smaller portions throughout the day or try a slow-feeding dish to make them slow down.

• Keep your dog active. Make sure they get plenty of exercise and playtime.

• Change your dog’s diet. If you switch your dog to a new food, gradually introduce the food with their current kibble over the course of a week or two.

If those tips don’t work, you may want to feed your dog a mix of dry and wet foods. Make sure they are getting the right amount of protein. You generally want to give your dog more protein than carbohydrates, but too much red meat can also be the cause of especially stinky farts. Introducing a probiotic diet or supplement will aid in healthy digestion. Ask your veterinarian first if you’re considering giving your dog over-the-counter anti-gas medication.

What Are Some General Tips for Choosing a Healthy Dog Food?

Foods with low-quality ingredients can cause gas in dogs, so make sure to look at the ingredients that are used in your dog’s food. Avoid feeding your dog food that contains fermentable fibers such as chicory, inulin, pectins, psyllium, plant gums, oats, barley, beet pulp, fruit, or legumes. High-quality foods will consist of the following:

• One or more animal-based protein sources at the top of the ingredient list

• The words “highly digestible” or “low residue” on the label

• Minimal to no chemical preservatives

When Is It Time to See the Vet?

If your dog still has excessive gas after you’ve changed their diet, it may be time to visit your vet. Not only is your dog’s gas uncomfortable for you, but flatulence can also cause your dog physical discomfort. If your dog has a medical problem or food sensitivity, their gas may be accompanied by the following symptoms:

• Weight loss

• Change in appetite

• Vomiting

• Diarrhea

Schedule a visit to your veterinarian if your dog shows any of those symptoms.

Let's talk about cat poop!

Healthy Poop in Cats

How often should a cat 'go'?

The general rule of thumb is that a cat should poop at least once a day. However, the frequency of your cat's bowel movements is affected by multiple factors including the age (i.e. kittens defecate more often than adults), diet, exercise, and health status (i.e. IBD, hyperthyroidism, parasites, CKD).

Because of this, the exact frequency of the bowel movement will be individual, and you should monitor for its fluctuations instead. If your cat's bowel movements start to differ from the normal frequency for longer than a day or two, it is advisable to pay a visit to the vet and resolve the cause of the change.

What does healthy poop look like?

Healthy cat poop should be deep brown in color (but not too dark nor black) and malleable in consistency (similar to modeling clay; it should be firm enough to leave little to no residue on the ground when picked up, yet pliable and not too hard). Poop should be passed in one piece or a few smaller pieces of somewhat cylindrical shape and segmented appearance. The odor shouldn't be too foul, although this can be variable.

Unhealthy Poop in Cats

The key signs to look out for in your cat's poop are the consistency, shape and color. The stool's consistency is directly influenced by the amount of moisture in it, which gives you an insight into the colonic health. The colon (or the large intestine) reabsorbs the remaining water and other key nutrients from the indigestible material, thus solidifying this material into the firm stool. The consistency of the stool can be descriptively scored to help you recognize if your cat's stool is healthy.

A comprehensive fecal scoring guide was described by Purina. According to Purina's guide, the consistency of the healthy stool can be scored on the scale from 1 to 7. The healthy stool (as described above) is scored with 2, while the stool that is too hard and dry is scored with 1. Scores from 3 to 7 are reserved for moist, mushy or liquid stools.

Hard stool (score 1) is typically a sign of constipation, which can be associated with dehydration, colon obstruction or certain metabolic and neurological conditions. Thus, if you notice that your cat is passing poop that is too hard in consistency, you should pay a visit to the vet and address the issue. The hard poop is passed in smaller, more spherical pellets which leave no residue on the ground, and the passing itself requires more effort.

Soft, mushy or liquid stools (scores 3-7) can be a sign of bacterial infections, intestinal parasites, or food intolerance. If your cat's poop is moist on the surface, thus leaving residue on the ground, but retains the shape and form when picked up, then its consistency can be scored with 3. This poop has little to no visible segmentation, but is not considered to be an alarming sign.

If the poop is so moist that it feels saggy and it loses form when picked up (but does retain a logged shape when passed), then the consistency can be scored with 4. Furthermore, if the stool is passed in a pile rather than the logs, then it is scored with 5. If your cat passes liquid stool with texture but no shape, then the consistency is scored with 6. Liquid stool without any texture nor shape is scored with 7.

Soft or fluid stool (as described by the scores 4-7), accompanied by a more frequent bowel movement, are referred to as diarrhea. While the causes for diarrhea are variable and often multi-factorial, this state is considered to be an important, sign of underlying problems and is a legitimate reason to consult with your vet. Sometimes, diarrhea can be caused by stress (i.e. moving to a new environment or bringing in a new pet), or food allergies and intolerance.

Other times, however, diarrhea can be a symptom of a disease, a bacterial infection, or even intestinal parasites. If your cat is suffering from diarrhea, make sure to closely monitor the frequency on your cat's bowel movement, so you can report it to your veterinarian. Keep an eye on other signs of disease and injury and the changes in your cat's behavior. This will be key for the diagnosis of the underlying cause.

Contact your veterinarian ASAP after spotting the symptoms, especially if diarrhea persists for more than two days and is accompanied by lack of appetite, lethargy, or vomiting. The veterinarian will diagnose the underlying cause and help you design a special recovery diet for your cat until it recovers.

The stool is a direct insight into its colonic health. It can help you recognize if your cat is eating the right diet and drinking enough water or if it's suffering from certain health problems. So, the next time you clean the litter box, make sure to quickly inspect if your cat's poop is healthy! A healthy cat is a happy cat.
