It's 'way too late to give helpful advice to Peg about the cat carrier but, just in case someone else reading this thread has the same problem fitting a furry "starfish" into a plastic box, here's what my vet suggests (and it works!):

Place the cat on the floor in front of the carrier butt first, facing away from the carrier door. Put the flat palm of your hand in front of the cat's nose and move your hand toward the nose. The cat will back away, into the carrier (if necessary, gently guide his butt into the carrier with your other hand). Keep moving the nose-hand toward the cat until (s)he backs into the carrier completely, then close the door quickly.

Peg, I hope your new place is working out well for you and your kitties!
