I cant really help you, but i know the feling.
Ive had to leave my kitty behind at my parents house because of not only bubby but because of the trouble of moving her from parents house to DP's house, plus she has a bigger yard and 2 other cats she lives with at my parents house...
It was a hard decision but i figured, i can still visit her, and maybe at a later date i can move her to DP's house with me, when bubby is a bit older.
Wish i could help more, maybe run a search on google?
