I met my cat about 5 years ago in my yard, and we think he was 5 or 6 years at that time. I don't think he's ever had a home, thus probably feral. It took quite some time for me to be able to touch him and he was (and still is) very skittish. Slowly, he decided he wanted to discover what was indoors, but discovering did not mean staying. Eventually, he began coming in at night to eat (only to eat--not stay all night), although I also fed him outside earlier in day. Then, he'd sit with me on the couch for awhile, but I had to keep the door ajar, which he always checked. Eventually, I was able to close the door without him panicking or constantly checking it because he trusted that I would let him out when he wanted. I should mention that at one point, he had a wound from a fight, and I tried to keep him in with a cone per vet's instructions, but after spending 48 hours with him going a little crazy to get out, I relented. Presently, he sleeps during the days, but only outdoors. He can't relate to being indoors during the days. He's inside part of the night--may come in around 9pm, eat a little, sleep for awhile on the couch with me, but inevitably goes out again. Then, he may come in and out until he settles down with me in the bed for a few hours (loves to cuddle, kiss, & groom me---amazingly), but can't make it through the night without going out. He refuses to use litter box, but that's usually not the reason he wants to go out. Even in the rain, he'll go out, just to be out. I don't have the option of a cat flap and because I don't want him out any. more than necessary, I have a motion sensor camera that alerts me to when he wants in, which works well, but sometimes, he only wants to eat more prior to going outside again, and other times wants to sleep some more. Needless to say, my sleep is off and on. One of the problems with this (other than disturbed sleep), is that being out all day makes it difficult for me to get him to the vet--which is major problem. I have a very large yard and he sometimes sleeps at property next door, but either way, it's just about impossible to get to him and get him in carrier for vet. If I keep him inside, I would do it early morning (between 5 & 7) which is usually the last time I'll see him before he goes off to his daily hibernation. So, I'd have to deal with his crying and hiding for what could be hours before vet appointment--and then, of course, there's the challenge of getting him in carrier--if I can get to him. Also, there's always a change in his behavior after I try to get him in carrier--more skittish, wary of me, etc., and if I have to do this for hours (it would be the first time), I fear the consequences, in terms of his not wanting to come inside anymore, etc. In addition to being feral, I believe he has PTSD from being trapped in structures a few times, and it's just heartbreaking to see what he goes through even if I don't open the door fast enough for him!!. I need to take him to the vet and this is just hanging over me like a dark cloud until I can get him there. Any suggestions?? Thanks!!
