I just bought Popsicle a new toy a few days ago.
It was a hay ball, a sort of ball weaved from straw/hay sort of thing, and stuffed full of timothy hay. For rabbits and chinchillas. They're meant to chew it, and reach inside and grab the hay and such I think.
Today, I was like... "where's the ball gone? ... are those long strands of rope looking thing... yup, looks like utter annihilation..."
Popsicle confuses me in certain ways. He likes to deposit unfinished treats and edibles into his food bowl, making me think he recognizes it as his food bowl. ... but he also poops in it a lot. hmm.
