What do they like to play with? Cocoa seems to keep herself busy all day, but it seems like she's just checking stuff out. I'd like to get her some fun stuff of her own. She has a rope-wrapped carrot....thing but pays zero attention to it. Also, I once threw a little stuffed duck in her direction sort of by accident and she ran up and bumped it. I thought she might've been playing with it but I guess she could've just ran into it. Any ideas?
