We got Em an electric cello and the box makes a great playground. Huxtable fits through some of the holes I cut; I guess they all do, but it looks funnier when the fuzzy ones slip through a small opening.
Hamilton has a little meow, not loud, but fairly mature. Huxtable’s squeak is so high it’s practically a whistle. Hale Bopp does the silent meow: visual with a little bit of sound from the lips opening. Hollywood doesn’t tend to ask for anything. Most of the meows are the “Pick me up, please” type.
