What is FeLV and FIV? Monique Conway with Humane Society of Southern Arizona explains what Feline Leukemia Virus and Feline Immunodeficiency Virus are and what it means if a cat you adopt has it. During the month of July ALL cat and kitten spay and neuter surgeries will be ONLY $15! What could make the discount even better? This July, core vaccinations will be included at no cost with each cat and kitten spay and neuter surgery appointment! Cats and kittens must be between 3 months and 4 years of age. Appointments are required and space is limited.
