New friends?

Yesterday, we added to our happy family. We were already the providers for one very prima dona-ish mackerel tabby who had a personality about ten times her body weight (which is about 7 pounds). We have added two behemoths to the mix: a gray and white shorthair and a massive black fluffball (neither one of which weighs less than 15 pounds). Sigmund and Remus join Salome to make us a three cat household. Unfortunately, right now none of the three seems happy about it.
