Hey guys! I would like some opinions! Me and my new husband are moving into a brand new apartment together. I have a 2 year old spayed female and his family has a 9 year old spayed female. I know for a fact my cat is VERY territorial but I also know she's quite a bit nicer to cats in neutral grounds and if I take her into another cats territory. His cat is the same way. Now I understand most articles discuss introduction of a resident cat to a new cat and there is the separation and the slow introduction. However, I'm struggling with this because I feel like if I separate them in the beginning I will risk them becoming territorial over the rooms they are in. Now keep in mind. If it doesn't work out the older cat will go back to the home she is in now with his parents but I really want it to work out cause no body likes her and she doesn't get appropriate care, feeding or play. And I quite feel bad for her as she's a very nice cat (they got her 6 years ago and she's developed urinary issues which I'm sure are due to a too small litter box not being cleaned often enough) and therefore they don't want her. I really really want them to get along or at least tolerate each other. Any thoughts?
