A shot saves lives. The Pennsylvania SPCA is offering low-cost vaccines for a highly-contagious feline disease. Cats and kittens are at risk of severe illness and even sudden death from a common virus called feline panleukopenia, caused by the feline parvovirus. The virus can survive up to a year in the environment, so healthy, unvaccinated cats can become infected without ever coming into direct contact with an infected one. The virus is difficult to destroy so it may also be spread by contact with contaminated objects, even if they’ve been washed, such as food bowls, litter pans, bedding, and shared cat carriers, or by people who have been in contact with an infected cat (on hands or clothing, for example).
