I have met a couple of hamsters and have a Ferret that would make a real good argument for Vampire animals but I know what you mean it would seem very unlikely that the little things would be Vampire but dogs or wolves I don't have a problem with Dogs and Cats etc.
I suppose really the jury is out on the Chupacabra, having never seen a real one its a bit hard to say for sure but the evidence so far would seem to point to them being Vampyric.
The place you go from here is only talk to the ones who know you exist Faith (at least about pegasus anyway) and that way you don't have to worry about suddenly blinking out of existence at an inopportune moment.
It leaves a funny smell and a cloud of smoke that's really difficult to explain
