My kitty is a poorly controlled diabetic so far. He's 6 units of Lantus 2x daily, sugars stil in the 300-400's. 1 month ago he was diagnosed w/ a UTI which developed into a kidney infection 2 weeks ago. He was hospitalized for that for 4 days, put on stronger antibiotics & on pain meds ( Buprenex) ever since. Throughout this whole time (starting 1 month ago) I noticed he woulnd't sit his butt totally to the ground and when laying on his side, his butt was always elevated. We all assumed it was maybe a burning sensation in his genitals or pain from the kidneys. He seemed to be getting better though all the way around though & I am still to give antibotics for 6 weeks. Suddenly on Sunday he stopped eating & was EXTREMELY painful & hunched & his butt even more elevated. I noticed the base of his tail looked a bit enlarged too. He had xrays & ultrasound yesterday & they didn't show any masses or stones. Bloodwork shows elevated globulins which could be a sign of infection or cancer . He pees & poops no problem & he didn't seem to be in pain when the dr touched his kidneys although the whole rear area of his body is sensitive it's mainly his BUTT/TOP of TAIL. He's on stronger pain meds & it's taking the edge off but he still looks so uncomfortable. My main question: HAS ANY OTHER DIABETIC CATS SHOWN SIMILAR SYMPTOMS WITH THE BUTT BEING FAVORED & ELEVATED? Could it be weird neuropathy? Please any ideas are appreciated.
