Tabby cat

　　This disease mainly infects cats, but other felines (wild cats, tigers, leopards) can also be infected and develop the disease. Kittens have a special susceptibility. Infected animals are the main source of infection; the virus is excreted through vomit, saliva, feces, and urine, contaminating food, eating utensils, cat shelters, and the surrounding environment, leading to infection after susceptible cats come into contact. The main routes of invasion are the digestive and respiratory tracts. Recovered cats may still excrete the virus through feces and urine for weeks or even over a year. During the acute stage of the disease, fleas and some blood-sucking insects can also transmit it. Pregnant cats can transmit the infection vertically to their fetuses through the placenta. This disease is mostly seen from late autumn to winter and spring, with cases between December and March accounting for over 55.8%, and a 19.5% infection rate in March. The course of illness is mostly 3-6 days. If cats survive beyond 7 days, recovery is likely. Mortality rates generally range from 60-70%, and can be as high as over 90%.
