He's so CUTE! SL got his new Kuma cat in October, and he even isolated her in the bedroom during the day, and the bathroom at night for a while, but it still took a while. She and Tigger are now perfectly content in the same room, and there's been a little bit of licking and kissing and much chasing, but it's only been in the last few weeks. They fight sometimes, but get along all right, and it's clear that they spend some time together when SL's at work. I say give it time--he should stop worrying so much about things, as well, after some time. Kuma liked playing, but didn't seem to know what toys were, and now she's got a basket-full. Which don't last long, because she kills them. She was terrified of so many things, but she's finally used to most sounds, and loves cuddling. :-) Good luck! And don't be afraid to isolate him and give Olive some mommy time.
