His creatinine has risen to 2.5 from 2.4 and his BUN to 29. These numbers are not surprising as I was told that as a cat with renal failure, his indicators will be like this. The vet Dr L said he is maintaining his levels so she was not unduly worried.
The other test I had done for him is an FIV/FeLV test as we live with an FIV+ kitty, Megat, and the whole gang had a tiff with him. Megat had 2 puncture wounds that got infected. So I have to do the test on the other 3 boys involved. Toro is FIV/FeLV negative. This is good news except now I have to decide if he should get vaccinated against FIV. He is an indoor cat and microchipped. If he ever escapes, I hope to get him back. If he is vaccinated against the virus, he would show positive but it is not possible (yet I read) to determine if he is positive for the virus or positive because of a vaccination. This is my worry as cats may be euthanised just because they have the FIV virus!
