Alright let me start this off with some context, I am a 18 year old senior who's life revolves around animals. At my house I have a cat and 7 reptiles (all mine), but at my grandparents who i vist every weeked, has not just a cat, but a spawn of pure evil. Now this cat we bought from a home as a kitten and raise it up to the evil it is today, it has never been abused and has a life full of enrichment amd everything it needs. But even so this cat does not let anyone pet it, it never purs, it breaks stuff, attacks at random, and has a ever growing desire to murder. My cat at home is the complete oppisite, so needless to say I was taken back by the attitude, and tried many things to correct this behavior. But recently I have had this ever burning passion to strangle the cat, step on its neck, or simply kill it in anyway possible. This started when the cat decided to ######6 fling one of my gecko enlosers across the room, break in, and eat its tail. It must have thought the taste was good too, because now she wont ######6 leave any of my enclosures alone and i have to hide them in the basement. Ever since she touched my precious child, I've felt this way, and I have given up on trying to fix whatever mental problem this cat has, because whenever I see it, I get a visual image in my mind of abusing the thing. This freaks me out, I would never hurt my other animals or even my cat, but this ######6 evil has me going crazy, and these thoughts i have need to stop.
