Boo had a rough night again. He was doing ok until I gave him the Buprinex before bed, at least I think that's what caused his vomiting. I didn't get into bed until 3:00 AM and at 4:00 he started vomiting. I watched him in the litter box this morning and only a tiny bit of urine came out. I hope that the tumor isn't blocking him again already. He barely had time to recover from the last few days. He didn't eat any breakfast this morning so I haven't had the heart to give him his other meds yet. I'm going to stop the Buprinex and give him Metacam instead but he still needs his thyroid med and the antibiotic b/c Dr. Lee said that some cats get a UTI after catheterization. I feel so bad now. I hope he can snap out of this. Please say a prayer for my handsome boy.
