Abstract: Feline herpesvirus（FHV）and feline calicivirus（FCV）are two main pathogens that cause feline infectious diseases. FHV and FCV can cause conjunctivitis, rhinitis, oral inflammation, etc. in cats, or accompanied by pneumonia, fever, etc. Symptoms are extremely harmful to the health of felines. This paper mainly analyzes the prevalence of virus in the local area and the relationship between incidence rate and pet species, age and other factors, by investigating the cases of cats infected with FHV and FCV in a pet hospital in Zhengzhou from February 2020 to July 2021. The results showed that there were 72 FHV positive cases and 120 FCV positive cases, accounting for 37.5% and 62.5% of the total incidence, respectively. The most susceptible species for FHV are Chinese pastoral cats and British Shorthair cats, and the most susceptible to FCV are Ragdoll cats and Chinese pastoral cats; FHV mainly infects cats under 3 months and over 10 years old, and FCV mainly infects cats under 3 months and 3’6 months old; the incidence of male animals is slightly higher than that of females, but there is no significant difference; FHV is susceptible to infecting animals in winter and spring, and FCV has the highest infection rate in spring and summer. The positive rate of FCV is higher than that of FHV, and the incidence of both diseases is related to species, age and seasonal factors, but not to gender.
