Thank you for all the replies, I really appreciate it!
Here’s some more information about my boy Sammy:
Last year, at his regular check up, the kidney values were a little high, so the vet checked him and said he had a UTI. He got antibiotics, then more antibiotics, then stronger antibiotics, which were impossible for me to give him. He would gag and drool for hours, even with a pill gun. Until he would just hide under the bed and never come out. So we stopped those pills and he got an antibiotic injection, still UTI. Another antibiotic injection. Then a break. This year at check up, again his kidney values were off. His urine was normal, but the bladder ultrasound showed a lot of inflammation. (I apologize, I used the word infection instead of inflammation in my original post; English is my 3.language, sometimes I misuse words, my first language is German...) Anyhow, he was given Metacam, but got bad diarrhea from it, so I stopped it. His insulin is Novolin and he’s on 1.0 units in the morning and 1.5 units in the evening. He was getting science hills prescription diet until recently, when I looked closer at the ingredients and it seemed to be I’d been feeding him garbage (I could be wrong

), now he gets Tiki Cat (the kind with highest protein as was recommended by a vet tech working at the pet store I buy his food). He’s a total kibble junkie, but I convinced him to eat some canned food for added hydration, he also has a water fountain to invite him to drink more; he seems to really like it. He’s had a urethra blockage a few years ago, maybe in 2017 or 2018, and was hospitalized for that. The day I got him back, I had to rush him to the emergency vet in the middle of the night with severe hypoglycemia. His glucose was so low, they couldn’t even get a reading! He recovered well and I learned to better recognize the signs of it. Two more midnight incidents of hypoglycemia in 2018 & 2019 and he’s been better since (knock on wood ). I got the water fountain after the urethra blockage and also bought a water filter pitcher for the pets after that. I check his glucose myself once a week.
I’m so glad I found this forum, sometimes it feels very overwhelming to care for him, but I’d do anything for my babies. I also own another cat, Rory, she’s in stage 2 kidney disease and I have an Australian Shepard mix, Skye; she’s Sammy’s best friend. I’m not sure if he’s in pain because of all the inflammation in his bladder. I know cats often don’t show it. He does sleep a lot and usually lays on his side. He does sometimes seem to have trouble walking and can’t jump very high anymore, so maybe arthritis too? It definitely got worse when he was taking Metacam, he’d even wobble and tip over, or walk a few steps and then his legs seemed to give out and he’d plop on his butt. That went away when I stopped the Metacam. I can’t remember the name of the medicine I was told to give him now. They are capsules and they’re also prescribed to humans for anxiety and the vet tech I was talking to mentioned Sammy would be too high after getting these to stay mad at me for long, after I said I had concerns as I am aware that I’m very bad at giving him pills... ok, sorry, long story, so I’ll stop now. Thank you!!!
