Thanks everybody. Just wanted to give a little update. I covered the windows last night, and I believe everyone slept through the night - I sure did. I only woke up once to find Peanut on top of me, well, more like half on and half off. I must have rolled over, not realizing she was on me, and she didn't bother repositioning herself, so her front part was on the bed and her back part was still on me. Tubby did start stalking her this morning, but not as bad as usual, and as soon as Terry headed for the kitchen Tubby forgot all about Peanut 'cause I'm sure he was thinking "Milk, milk, oh boy daddy's going to give me some milk!" So, this might just be the ticket. I'll have to go to Petco and check out some citrus spray or something, although I will be covering the windows everynight. I really hate to do it while we're gone because I know the snots really like looking out them and it would definitely provide entertainment while we're gone, but Peanut doesn't need all that kind of entertainment, so they'll be covered and Tubby will just have to deal with it. Maybe I can leave a chair by one of the windows that isn't conducive to the outside cat or something.

Anyway, night one went well, so hopefully this is the solution. I'll let you all know what the vet says, and keep everyone posted with any updates.

Thanks again for all the suggestions and support. I think it was Wayne that mentioned once that once you post something, the kitties stop doing the offending behaviour. Seems to work!
