Expiration-related neurons in the caudal ventral respiratory group of the cat: influences of the activation of BoÂ¨tzinger complex neurons. Author links open the overlay panel.
Feline leukemia is a transmittable virus that can damage a catâs immune system. It can sometimes be hard to spot because not all cats with the disease will show symptoms. The virus can be in a catâs bodily fluids including saliva, urine, feces, and blood, and can be passed through direct contact or even grooming.
Kittens less than four months old are susceptible to feline leukemia, but healthy older cats are resistant to infection. Of all cats that die of cancer, about one-third will die of leukemia-caused tumors.
