Roommate Issue

So my roommate/friend and I are very good friends and also classmates (we’re in a professional program and so we see each other all day at school as well as at home). She’s a great roommate and I enjoy living with her. We have a second roommate who is moving out at the end of April. So we’re looking for a new roommate (we need a third because rent is too high between three).

The house we live in belong to my friend’s parents so it’s pretty much her house. Well when we first talked about getting a new roommate we were on the same page about everything- we wanted clean, quite and no pets. I have a cat that I recently rescued from a third world country- she was a stray up until about 3 weeks ago. She’s incredibly skiddish, high stress and very aggressive with other animals (where she lived stay cats were very common as were stray dogs so a cat would literally fight to the death for their territory as loss of territory generally meant death by the dogs). She’s also very likely to have FIV which is basically HIV but for cats- I haven’t tested her because the process would be very stressful and because she’s an indoor cat and no other cats live in the house she is not a risk to other cats. So it was all great.

Well today my roommates Mum called and suggested a new roommate which is fine. But this girl has a kitten. My friend/roommate is all for it even though I’ve told her I’m not ok with this. I do not want to give FIV to another cat (my roommate just says we’ll let this other girl know so she can make an informed choice to take the risk). Nor do I want to be responsible my cat killing this kitten (she will very likely try and I have seen her do so in the past). But I also do not want my cat put through additional stress. She’s just been moved across the world which is a massive change. And in May I am moving cities for work (another stressor) and returning in August- which is a whole new issue because I will then bring my cat back to her home there will be a new animal that will also think the place is her territory. It’s just way too much stress for any cat let alone a cat that likely has a disease which is made worse by stress.

I have told my roommate all of this. And she doesn’t seem to care at all. Just keeps saying we’ll see how it goes and if it doesn’t work out then we’ll figure it out. Right now all I want to do is move out because I want to protect my cat (and this kitten). But my roommate is a very close friend (who’d think she’d listen to my feelings about this so maybe we aren’t that close) and I can’t have this become a huge deal either. I just have no idea how to tell her this isn’t ok in a way she’ll understand, because so far the only thing I haven’t said is ‘if another animal comes into the house I’m moving out’. And I feel like that’s just going to cause drama and hurt feelings which is what I don’t want to do.
