Alone, with one cat. I have yet to have someone I am involved with at my place. I have had some super cats, but things have happened to the ones I was bonded with.
Have had in the past as many as three other people here, my brother, a good friend and his BF.
Recently had my Uncle here for several months, it was a strain, and exhausted my reserves.
Have tried several times to have paying roommates, it has not worked out, they have so far turned out to be serious flakes. I would be glad to have someone I wasn't involved with stay here for free if they were pleasant company.
