I think they're trying to tell you that the beds are not big enough :)
If you get smaller beds, they'll turn you in to the Greyhound adoption authorities! Best not take the chance! lol
Polly and Song before her seem to often lay half in and half out of the bed. Looks uncomfortable.
I rather think they may be punking you. The worm is especially suspect.
Greyhounds are definitely silly that way! It always makes me laugh at their crazy positions on beds. Glad you are blogging again, I followed you a long time ago but then I thought you gave up on the blog - it's a little late, but welcome back :)
