Perma is very possessive as well. Not of particular spots (except from my bed and my sock-drawer which I let her sit in only when I'm getting ready to go to work in the morning ) but of me. When I adopted Foxy she terrorized him and would not let him near me. Funny thing is that she has fully accepted him now (I suppose because at 10 months he is sooo much bigger than her already ). She is still the boss but now they love to play together and he is allowed to spend time with us, only the sock-drawer is still a no no (from both of us really, Prema considers it hers, I prefer the sox to remain in the drawer). She just ignores Maya but doesn't dare to bother her since Maya was there first (and is also bigger than her )
