A highly contagious and often fatal disease affecting cats is spreading in East Idaho, prompting warnings from animal shelters and veterinarians for cat owners to ensure their pets are vaccinated. The Idaho Falls Animal Shelter reported a significant increase in cases of feline panleukopenia, noting that the virus spreads rapidly and is almost always fatal without immediate medical intervention.

Alpine Animal Hospital in Chubbuck has also observed a surge in feline panleukopenia cases recently. This viral disease, sometimes referred to as feline distemper, primarily affects rapidly dividing cells, notably in the bone marrow and gastrointestinal tract, leading to a severe reduction in white blood cell counts.
Symptoms of the disease can include lethargy, loss of appetite, vomiting, diarrhea (which may be bloody), dehydration, a rough coat, and fever. In severe instances, especially in young kittens, the virus can result in sudden death.
Feline panleukopenia spreads easily through bodily secretions, especially feces, and can be transmitted indirectly via contaminated food and water bowls, bedding, clothing, and shoes. Consequently, indoor cats are not completely safe from exposure, according to Alpine Animal Hospital.
Vaccination remains a key preventive measure. The FVRCP vaccine, a core vaccine for cats, includes protection against feline panleukopenia. Kittens typically begin their vaccination series at six to eight weeks of age, with follow-up booster shots based on a veterinarian's schedule.
Veterinarians are advising cat owners to verify that their pets are up to date on vaccinations in light of the recent spike in cases. Owners should contact a veterinarian promptly if their cats exhibit any signs of illness, particularly vomiting, diarrhea, severe lethargy, or refusal to eat, as early intervention can be critical for recovery.
