I feel bad posting this here but am hoping there are some animal lover's who may give me some advice, I was going to post on zoklet where my personality is better known but after seeing some recent posts there I don't know if I would get the advice I am seeking.
So about 6 months ago I took a cat in, she constantly visited my yard eating my dogs food and was in good health. She looked like a house cat someone didn't want any more, she was fat and not beat up, shiny coat etc. Whenever I would take my dog out at night she would come in the yard and we slowly bonded and I gained her trust. I found out she had no front claws so that also hinted to her having been someone's pet at sometime. Anyway, I got worried for her and gave her a home and for the first few weeks she wouldn't leave my basement where her litter box and food was but we became homes and she fit in well with my son and my dog.
She recently started pissing all over my home and if you know cat pee, you know how disgusting and vile it is. I am a little OCD with home cleanliness so this started to piss me off. I tried different litters, a second litter box and took her to the vet to make sure she didn't have any problems (she doesn't, she's also fixed and the vet agreed she must have been someone's pet not too long ago due to her health and weight etc). With a small child in my home I eventually got to the point where I told her "yo this shit isn't gonna fly", as much as it broke my heart to feel that way. I started feeling like maybe she was just a bitch and wanted to make her mark.
After having to clean my bed linens for the 3rd time (not the only place she pissed) I was done. I decided to bring her back outside and feed her daily, visit her and figured she did it once before she would be fine again.
WRONG. She was only out one night and today my mail lady knocked on my door to tell me a cat was in my side yard with their head stuck in the chain link fence. I panicked and ran outside, sure enough, it was her in her fat derpy glory on her back with her head stuck in the fence. I thought of calling animal control but I didn't want her euthanized. I got some wire cutters and cut the fence and got her out and brought her back in the basement and shut the door so she wouldn't pee all over the place again. She had no marks on her neck and wasn't showing any signs of pain but she is acting weird... won't eat (she hasn't the past few days) and won't move from this one spot in the basement. It sounds sick but I feel like she's dying and it's freaking me out and I feel horrible. I don't want to find her dead. I have no money the next 2 checks to bring her to a vet and this was obviously unexpected. I figured she would come back to my yard to eat but not commit kitty suicide.
I cried like a baby when I kicked her out and cried when I saw her in the fence and am about to cry thinking of her withering away in my basement for god-knows-why but pissing all over my house is not going to fly. I have bigger fish to fry than a cat being a diva. I have had cats growing up but never one who acts like this.
TLDR: took in a homeless housecat/stray, we were homies until she started pissing everywhere for no reason and she tried to commit kitty suicide after me putting her back outside and idk wtf to do.
Any advice would be greatly appreciated. I am a sap with a big heart but anything that could endanger my son's health and ruin the integrity of my home is a big "fuck no".
Also, shelters in my area require me to pay for them to take her in and word on the street is they will get put down anyway 90% of the time. I'm also wary of putting her in Craigslist because people are fucked and I'd like to know what happens to her and I worry someone may not be as tolerant of her acting out as I had been.
