This is wonderful news!!! I'm so happy to hear that Snow came home hungry, dirty, but none the worse for wear. I agree with you that it was probably all the strange smells and unfamiliar looking mommycat that upset the babies.
Okay now, Snow, your Meowmie missed you and your babies want you back. Plus your PT fans were pretty worried about you. Get yourself cleaned up, grab a few naps then it'll be time to settle in once again. Please don't ever run away like that again, okay?
