Feline Distemper in Cats: Symptoms, Causes, Diagnosis and Treatment
📝 Summary
Feline distemper, also known as feline panleukopenia, is one of the most common acute infectious diseases in cats clinically. It is a highly contagious, febrile disease caused by parvovirus infection. Kittens have extremely high infection and mortality rates, and affected cats typically show sudden onset, markedly reduced white blood cells, high fever, anorexia, depression, vomiting, hemorrhagic enteritis, and severe dehydration.
1 Overview
Cause of feline distemper: parvovirus infection
Transmission may occur through food, the environment, sick cats in the same group, or recovered virus-carrying cats coming into contact with parvovirus. Routes of transmission: the digestive tract—cats directly or indirectly contact contaminated food, feces, urine, and environment—and it can also be transmitted vertically from the mother cat.
Symptoms of feline distemper:
1. Affected cats are depressed and have reduced appetite
2. Biphasic fever pattern
3. Vomiting / diarrhea / bloody stool
The biphasic fever of feline distemper shows a temperature rise above 40°C lasting about 24 hours before dropping to normal, but after 2–3 days the temperature rises above 40°C again.
Prevention of feline distemper:
1. Vaccinate early
2. In multi-cat households, isolate sick cats promptly
3. Thoroughly disinfect environments where parvovirus may be present
4. Limit outings for cats that have not completed vaccination
When a cat with feline distemper has had contact with other cats, you may choose to give emergency preventive vaccination or inject hyperimmune serum to the presumed-healthy cats; the latter is recommended.
Diagnosis of feline distemper:
1. Complete blood count (can assess white blood cells)
2. Feline panleukopenia (FPV) rapid test kit
3. Blood gas analysis (can assess electrolyte levels)
Dilute a fecal sample from the cat and apply drops to the test kit. A positive result shows two lines; a negative shows one line.
Treatment of feline distemper:
1. Specific therapy: feline distemper monoclonal antibody; recombinant feline omega interferon; immunomodulating peptides
2. Symptomatic treatment: for vomiting (an anti-emetic such as Zhituoning); for diarrhea (omeprazole); and so on
3. Prevent secondary infection: anti-inflammatory treatment
If the sick cat is vomiting, withhold food and water during treatment, provide appropriate fluid replacement based on the degree of dehydration, and persist with treatment.
Note:
It is recommended to follow the veterinarian’s advice and provide evidence-based symptomatic treatment according to your cat’s condition. Avoid contact between healthy and sick cats, and thoroughly disinfect the environment if a cat in the home has had feline distemper.
