Unique Cat Introduction Situation
My lease is up, and I am moving in with my father for an indefinite period of time. The hope is that I will be moving in with my boyfriend soon and that this is just a short waiting period. Ballpark, I expect to be in my father's house anywhere from 3 months to 1 year.
I have a 7 yo cat -- female, indoor cat. I've had her for about 2 years. She is a pretty submissive kitty and also quite needy and talkative.
My father has two cats, 5 yo -- both females, sisters/litter mates, but they are outdoor/indoor. I would not describe them as feral by any means, but they do spend lots of time outdoors. One is clearly the alpha, the other is more submissive and a little daffy. They get along.
I just started the introduction yesterday. Munchkin's safe room has been set up. There has been some hissing and growling by the Resident cats under the door. Unfortunately, they did have a brief face-to-face encounter while I was moving Munchkin to the safe room. Both resident cats got quite aggressive (stalking, ears back, growling, hissing), but Munchkin didn't do much, just kinda looked at them. This meeting was accidental (I believed the resident cats to be outside). I gently picked up Munchkin and moved her into the safe room. They did not physically interact. Did I mess everything up with this???
I guess I'm most worried about screwing up my dad's cats! They are his cats, and this is their home, after all. I don't want to ruin the great friendship they already have (I've already witnessed some odd behavior between the two resident cats -- some minimal hissing, growling, etc.), and I don't want them to run away when they go outdoors. Unfortunately, I have no other options right now (no friends who will take my kitty in temporarily, etc.). I'm also concerned that this is a temporary living situation. I don't want to do further damage when I separate the kitties again months from now.
Also, my cat is very vocal and already wants to see what's outside of the safe room! Agh! She just yowls and yowls, which I'm worried will turn the other cats off her even more!
I think I underestimated how difficult this would be. I just feel drained. Support and advice appreciated!!
