My cat turned 20 recently. He's been quite healthy for most of his life but had been diagnosed with chronic renal disease. He does not take any medication and gets no treatment for this condition, however I do pay special attention to his diet and make food for him every week. He eats a combination of white fish, quinoa, canned pumpkin, a little turmeric, coconut oil and sometimes some added multivitamin for elderly cats which has taurine among other things.
Recently he broke his rear leg but I'm not sure how. This was around 1 week ago. I am extremely financially challenged so have no extra money to take him to the vet. Because of this, I rigged a homemade brace/splint which he wore for a few days, but he seemed so miserable that I ended up taking it off.
I wasn't even sure his leg was in the best position to heal and recognized that it may not even heal properly (which I feel horrible about) and considered that his age and lack of veterinary care could certainly play a role in how quickly he heals or whether he heals at all. It wasn't a full "snap" for lack of a better term, as it seems that one joint now has a "missing" or broken ligament or something of this likeness that would normally keep his leg in a natural position.
When comparing his rear legs, the unbroken one is held in place rather naturally and the affected one moves quite freely from side to side with a total variance of appx 90 degrees.. This makes it difficult for him to walk because the leg will turn sideways constantly as he walks making for a pretty odd gait.
I know it hurts him still sometimes because he will lift it up on occasion while he eats. He seems to be adjusting and getting better despite the injury, but has recently been sleeping in the litterbox very frequently. Sometimes he will lay down right on his poo and I have to clean it off of him which is disgusting. I wake him up a lot and move him to a cozy corner next to my bed with a nice blanket - but he keeps going back to the litterbox.
He also seems to be retaining gas in his abdominal area but it fluctuates. My mother's elderly cat had the same litterbox affinity soon before passing away so I'm pretty worried.
I don't want to lose my cat but I know that his time will come and I will need to accept it. I can't bear the thought of euthanizing him but I also don't want him to live in pain. Is there anything I can do to make this better for him aside from veterinary care?
Any suggestions are sincerely appreciated.
