Would really value advice from you knowledgeable people.
The farm where I used to keep my horse got a cat to keep the mice down, he came from a rescue, sad story, his owner had gone into prison, meaning as an uneutered male cat he was in council facilities for 18 months, very stressed.
He went to the rescue, he was neutered, tried fostering him and he attacked two people, hence looking for farm home. He was always 'my' cat, he would jump on my shoulder and I used to do all my chores one handed whilst carrying him. He then suffered a blocked ureter, emergency, taken to vets, when farm owners heard what cost would be said put to sleep. I asked if I could cover cost, they said yes and said he was mine. He came home to me to recover, had permanent catheter in, all good whilst poorly. I gave 2 cats at home, once he was feeling better, started spraying everywhere so I thought best he go back to the farm.
Subsequently, the farm has 2 more cats, he started stressed and spraying, then calmed down but in January had cat bite and I am about to take him to vet with suspected blockage again.
So I am really struggling, don't want to leave him at farm, should I try him at home again? If I call rescue, they would need another farm home and he is on expensive kidney food ( which I pay for), so how easy to rehome?
Would love to bring him home but is this best fir him or my 2 here? All advice welcome, thank you
