Dionne - the place you are moving out of...is someone else moving in right away?

If not, I wonder if a student or friend would house and cat-sit for you for a week or so.

Or...a long shot...if someone is moving in right away...do they love kitties and would hang on to them for a week?

One more thought (that's all I can offer as I am in Canada) - if you know of a small moving company that might take them in their carriers even to your mom's place, that might be an option. There are cat lovers in all professions.

Hope you find a way!
