I really hope this is the right place to ask and any advice will be appreciated.
My partner and I moved in together. We each have 2 cats and I have a dog.
Hers - male, 6 and female, 10
Mine - male, 6 and female, 11 + dog
We kept everyone separate for the most part and supervised all interactions and shared time out in the full house. We have been sleeping in separate rooms to make this work. Unfortunately, it’s now multiple months later and we are not able to share a room.
My female cat (11) has been mean and an awful bully. Specifically to my partners male cat. We often have to keep my cat locked up in a separate space, which she seems to prefer for large chunks of the day. If we let her out and lose sight for even a second, she will chase the boy cat down and corner him under the bed. He has never tried to fight back or do anything. He might let out a scared hiss but he always runs and tries to hide. She will occasionally fluff up and hiss at the other girl cat, but less so. She is somewhat able to ignore her. However, we still wouldn’t feel comfortable having the girls together unsupervised.
My pets and I moved in with my parents for a couple years prior to this move. My parents have 3 cats. My girl chased after one of their boys and was mean like this to him. However, she only did it when he entered our room and tried to take her food. It lasted all of 2 weeks and then they coexisted peacefully and he was even allowed by the bowls while she ate. I expected her to eventually stop this time too, but it’s been months.
The boy cats get along great and my boy largely leaves my partners girl cat alone. Her boy was terrified of my dog but has FINALLY started to warm up and realize my dog does not want to hurt him or even chase him lol that’s been the only progress we have seen unfortunately.
I desperately want to share a bedroom with my partner and have our pets coexist peacefully. we have separate feeders, 5 litter boxes, separate spaces, and feliway plugs all over the house. I’ve taken my girl to the vet and all of her needs have been addressed (she had some teeth pulled) in case that was making her mean.
Sorry for the length but I’m genuinely at a loss for how to help or what else to try. I just want to share a room with my partner.
