A few days ago a scrawny looking stray tabby cat came around crying plaintively and looking for food. He's a very sweet and affectionate cat and must have been a pet at some point. I took him to the vet but no chip. I've been feeding him and seeing if he might get along with the other pets. I'm willing to keep him if it works out. The dogs are fine with him and he's ok with them, he likes the poodle. But our female cat is hostile with him. She hisses, growls and vocalizes at him to leave. So far he has been submissive and retreats but a couple of times he has done little hisses back at her.
This is a new situation for me. How long should I give the two cats to get acquainted and determine if they will get along? I'd rather not take him to the animal shelter, but if the two fight then I will have to do that or try to find him a home by posting on Nextdoor. My cat is an indoor/outdoor cat and the new one would be too if he stays.
