Oh, wow, that would be so awesome! When I moved to Canada, before I met Rom, I brought my one cat in a soft carrier with me in the cabin. I think with three plus a baby that might be a little much for the trip back.
We'll drive it if we have to, but we're hoping we can find a safe way to get everyone to California a little quicker, and less painfully. Any advice you have is more than welcome, it's needed!
