My cat died of kidney disease perhaps stage 3 or 4. Could someone here give blood test results that are real bad. Just curious. I have researched everything. Plus there are other factors. Cat being a stray for 11 years or so, having abscesses and other issues, But to be tnr 4 months ago(March) seemed fine and very happy but to lose over 2 pounds from March till july. Then to become extremely affectionate after never being petted in 11 years. I have his blood work. I know alot about BUN and creat levels. Just curious what really bad levels are that would make it difficult for a comeback.He was put down a few days ago but trying to understand all the bloodwork and get outside thoughts on it. Thanks
