My sister's cat delivered her 4 beautiful baby tabbies today and she has been following around everywhere I go. She will not stay with the kittens unless I'm right by her side. Is this normal cat behavior and will it stop? I work 40+ hrs a week and I don't know how she'll react when home alone with them. As long as I'm right by her side she is doing a great job with them. But the second I leave, she panics!
