Is two too much?

[MoshisMum]

I live in a pretty big 2 bedroom apartment. Moshi is such a darling, but I worry she gets lonely. She has Smudge (my rattie) for company, but obviously they don't play together (and Moshi is scared of her when she's out of her cage!).

Moshi is an indoor cat and seems quite content to be so. She has her funny half hour each day when she rushes about, but other than that she's seems ok.

I had thought of getting her a friend, but the question is:

Is two indoor MCs in a two bedroom apartment too much?

Would appreciate your thoughts :-)
