Ok, the siamese is back. Definitely not afraid of people. I think it would walk right in the house. However, it's either not fixed, it wasn't fixed very well, or siamese end up with a weird little skin lump when they're fixed. Or maybe I've always had hairier cats. I don't have time to run to a vet now - should I take this one in and isolate? (and pray for my house while I'm gone?)
