So, I adopted a cat about two weeks ago who was unneutered and abandoned by the person who had had him for his whole life (2 years). I have been told by the vet that he's sweet and the friend who's been the middle man for this adoption told me he was very sweet and cuddly with his previous owner. I have one other (female) cat who adjusted extremely quickly to living with me (like literally it took her a couple days) so I'm not super used to a cat that like hisses and growls and spits when I come close to him and hides most of the day, but I've just been trying to give him space and let him come to me and only do things like changing the litter box and feeding him and stuff.
Enter the neuter: it was done 12/16 in the morning and he was home by 3 pm. I was told to check the incision sight twice daily and make sure he keeps the cone on, but after he somehow pulled the cone off and I spent ten minutes trying to put it back on while he hissed and growled and spat and swatted at me I am just at a loss about how I'm going to manage any of that checking. I want to give him space, but I also want him to heal well. I'm just feeling really helpless and frustrated about this whole situation, and any advice is very welcome!
He and my other cat have been mostly staring at each other and occasionally running around together, but they seem to get along a lot better than he and I do. I don't try to pet him and really just ignore him except for occasionally offering him my hand to sniff (he has never taken me up and usually hisses) to try and show him I'm not going to touch him if he doesn't want me to, besides when I NEED to. When I need to grab him to get him to a vet appointment (or put his cone back on), he goes full "cat from hell" and has drawn blood from me several times. I'm honestly kind of afraid to touch him and dread having to. I am mostly wondering how I can check the surgical site with minimal trauma to both of us, but I have an underlying question of how long I should wait before I know for sure this isn't gonna work out and I should start looking for a better suited home for him? I really really want this to work, I want this to be his forever home and I don't want to further his trust issues, but I am just feeling so helpless, I don't know what I'm doing wrong and I don't know how long I should wait before it's traumatic to move him AND everything has come to a head here. I'm just super lost.
