Hi! i'm new to the forum and am looking for advice to a cat problem i have. I've had cats for the last 29 years. My wife and i would each select a new pet after our old feiends passed on. Because of nature we would end up with a very young cat and a adult 4 to 5 years older. The cats always adjusted to each other. All cats were adopted from the humane society all muts, very sweet anamials. For the last 6 weeks a beautiful black cat had been hanging around our house. We live in the north and winter was giving us our last reminder when i couldn't take it any more and went outside and after 2 hours got blackcat to come to me. I got her into a kitty cage and brought her into the house. After trying to find the owners we finally gave up and decided to take here to the vet to have claws removed and spayed. A few days after i brought her home i decided to introduce her to her new friends which she proceeded to trounce. We seperated them until stitches and 10 days had passed and tryed again and again she attacked the other cats. We have tried the seperation with sniffing under the door etc. We spend different times with each pet. Blackcat is the most loving cuddlebug i have ever seen. We hate to give her up but feel a strong obligation to our two other cats. Looking for understanding
