What is the worst that can happen if my unsociable cat is moved into a house with other cat residents?

Okay, I am in a housing crunch. My roommates and I have to be moved out on July 28 and for some reason finding a place to live this time around has just not been easy! So, basically, I have this opportunity for cheap-ish housing in a really great house in a really great location but the friends I’d be living with have 2 cats. The cats are both super laid back. My cat, though, has never lived with another cat, and does this insane freak out thing whenever he sees another cat outside the window. To add to that, he has no teeth or claws. Both of my friends cats have their teeth and claws so I would be scared of altercation and Barry getting his ass wooped. But like I said I’m not sure that these cats would even be into sassing or fighting cause they seem so chill.

I just don’t know if it’s worth the risk to move into a place and have it stress out my poor Barnabus so much….he has become easily and extremely stressed in the past over things like moving, me leaving for a short period of time, not enough attention (sometimes he wont let me sleep)....anyhow, he’s a bit of a basket case, and he’s pretty social and likes people, but other cats seem to be a real issue. So could I totally ruin his life by making him live with other kitties? I don’t want to do that. I don’t want to stress him out either. He’s 10 and should be living as leisurely as he likes (he’s a king) so I don’t want to cramp his style.

It also may be relevant that we’d all be moving in at the same time. They don’t already live there.

Please shed some light!
