Regarding Snickers' xpen: I'll be curious to hear from you if he is territorial about it or if he allows you to use it for Reesie.
Max would not let me use his wire crate for Teddy even though Max doesn't use his crate for anything. It just sits in the corner of my bedroom. Teddy slept in a double xpen when I first brought him home and I tried to put the crate in the pen for him to have a little den. Max went nuts. I had to buy a second crate. Silly boy.
Wishing you a great homecoming for your new baby.
