Those are definitely unusual and unique!
They don't really look inviting though. My yorkies like soft and cozy and I think none of my pets would get in that pink one. They would feel like they were being taken away somewhere

never to return by aliens

or something.
They would probably use the croc shoes but that thing is really ugly IMO. I don't even let my kids wear them,

you think I'll put my precious babies in there?
