Completely not the same thing... but I had to add it.
My bf and I were going through some problems a while back when I started gettting really homesick after moving to Canada from England and he said if I did want to move home that I could take Bumper because I couldn't ever live without him.
We occasionally argue over the amount of time I spend on the cats (or on the catforum when he wants to check football scores etc) but usually the cat wins and he copes with it ok.
It must be hard with him having a non pet apartment, but its great he likes Kilala... and I am sure things will be ok once you move together. I miss my cats when I am away, but try not to worry too much, they are very independent and can cope for a night. You also have social needs etc and being down over missing Kilala may make your boyfriend resent Kilala to some extent as he will feel that the small amount of time you do get to spend with him isn't quality time. (And trust me, I know how a family business leaves no time for a cat or bf).
Good luck, but try not to worry too much!
