Interesting topic!

For Scooter, I wish he didn't have a behavioral problem and pee on the floor. I feel so bad that he has to be in his cage/playpen whenever we aren't there to keep an eagle eye on him. If only he knew this, because I want him and Marius to be able to play together during the day

It appears that a lot of issues are around litterbox behavior. Interesting....

For Marius, hmmmm...he's my baby boy. I love everything about him! Maybe...not scratch the carpet if the door is closed, or get into things so much...but he's so cute! LOL LOL

Sergei...well, I really don't know him and his purrsonality has yet to develop!
