Help getting our cat to accept this feral
Good morning! I'm here looking for help with my trying-to-be formerly feral cat and another cat we have. Phil is a reluctant formerly feral, he was attacked by a dog 6 weeks ago and has damage to a let that means he can't jump and in this part of the Mexico city we're in, jumping is necessary for survival. He sooo wants to be back to his old life outside. But, here he is, reluctantly in our house, hoping for a way outside. We have three other cats; two are not at all concerned with Phil's place here, but Lupita, a 9 month old, is not thrilled. She had been hissing when he was near and had made lunges at him a few times. I'd been treating the cats with chicken, letting Phil be as far away from the others as he wants, thinking Lupita (who is very food motivated) and Phil would over time get closer to each other during these sessions and Lupita would begin to see Phil as a positive, tied to the chicken treats. We had felt things were actually improving over the last few days; Lupita has been non-reactive when Phil passes by near her, but last night, it all came crashing down. Phil and Lupita have both been fixed. Phil has been here for over 3 weeks. He spent the first two in a room by himself, then with a baby gate in the doorway so everyone could see each other and get acclimated. Thre were no altercations or suggestions of problems during the baby gate time. He's had run of the house for about 1.5 weeks now.
I was on my computer with earphones on so didn't catch exactly what happened, but I was suddenly aware of a lot of noise coming from one side of the house. Pulled my earphones out and it was clearly a loud cat fight. I jumped up and Phil and Lupita came running out of the kitchen, both completely fuzzed out. Now, I must tell you, we have had several incidents of loud cat fights on our roof and honestly, perhaps it was their reaction to a loud fight just above them? I thought I heard some growling after they left, but maybe I was hearing one of them? Since then, Lupita has been more vigilant against Phil, guarding doorways to a room he sees as his. We don't allow her to continue and currently, she's gone back to her usual self, but I'm wondering if anyone has suggestions for helping Lupita be more calm about Phil? I'm thinking about using those pheremone diffusers, but honestly, I haven't had much luck with them when used with other cats. I'm going to try diffusing lavander essential oil for now becuase it's what I've got, but any, ANY suggestions that might be helpful, I'm more than open to hearing!
Sorry this is so long, thanks for reading! Photo of Phil (upper right)) while I'm getting their dinner ready (he eats in a separate room from the others)
