2. The Smalls was kind of mopey this morning and had me worried but he has now changed his tune entirely. He just fought for the top of the cat tree, and won!! Biggie put up a valiant effort, but Smalls was all MINE MINE MINE! He has not shown much interest in the tree or any really joint effort lately. But now he's playing with the wire toy with Biggie and while he gets the top bunk, he's letting Biggie stay on the lower one.
The string is a shoelace being used to stabilize the arm of that top basket that Biggie broke off!! I wood glued it back into place and likely, once the glue dries, that will work fine. The shoelace is to hold it there until the glue can cure. I didn't even try to mark it off limits. That would have failed right from the idea stage.
