You obviously have a lot of experience treating both FeLV+ cats and kittens. He (Kitty) will be 12 years old this coming Spring or Summer. Thank you also Kat. I remember taking him (Kitty) in from outside when he was one year old. I am positive the Vet. did a FeLV test on him then and it was negative at one year old. It surprised me him (Kitty) being diagnosed this old with FeLV. </div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">I had an 11.50 year old cat (Mork - indoor only who I got from a shelter as a kitten) who died in 2014 of FIP (also diagnosed with it very late at age 11). I am not sure how these 2 older cats of mine contracted these diseases and how Mork died from it late in life. Does an older cat's immune system get much weaker as they age? </div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">The 11.50 female indoor only cat (Snow White) appears just fine. I took her in from outside the same time as Kitty at one year old. She tested negative for FeLV at one year old also. </div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Thank you very much again, </div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Jason</div></div></body></html>
