About this condition
A highly contagious viral disease caused by feline parvovirus that destroys white blood cells and intestinal cells. Mortality is very high in kittens; the virus survives in the environment for extended periods, making vaccination the most effective prevention.
Common symptoms
- Sudden fever and lethargy
- Severe vomiting and complete loss of appetite
- Watery or bloody diarrhea
- Rapid deterioration and dehydration
Common causes
- Infection with feline parvovirus
- Contact with feces, vomit, or secretions of infected cats
- Virus-contaminated environment or equipment
- Unvaccinated kittens (highest risk group)
Prevention (husbandry & daily care)
Regular vaccination (FVRCP) is the most effective prevention. Quarantine and test new cats, and regularly clean and disinfect the environment.
