The cats received toys from my mom and my sister for Christmas: two big honking bags of toys. So far, their favorites are the spheres. I can tell because they play with them like mad and then stash them for weeks, which is what they do with their favorite mousies. Stanley also likes to snuggle his, though.
He actually slept with it that way before he spirited it off to its next hiding place. We’ll probably see it again around Halloween.
