So I've acquired yet another cat.
Tabbatha had to fob her cat Midnight off on others when she moved into her current residence, but Midnight was a bad fit with his new foster family, and since no one else would take him, and no one wanted him going to the Animal Rescue League, he wound up here. In a tiny apartment. Where two cats already live.
Delmar, the pscychokitty his own bad self, immediately went apeshit, growling and hissing and spinning in circles in much the same way Lynda Carter used to on the old Wonder Woman show.
This display sent Midnight off into a growling frenzy of his own. Not that these two are mixing it up, mind you--they're pointlessly growling from seperate corners. Midnight will hop up on my lap, purring, affectionate, look over, see Del and suddenly start growling, then turn around and slap me in the face.
Fortunately, he's declawed, so his blow just lands with an ineffectual fwap, so it's more comical than anything else. Still, another cat whose emotions turn on a dime--Great!
Monika, meanwhile, really doesn't care--she spent years as Mom's cat, and is used to new creatures arriving in her life. As long as it's understood that she is the prettiest one and receives the attention due her status, Monika is happy.
Presumably they'll all eventually learn to tolerate, if not actually love, each other, as families and nations do. If families and nations were fur-coated and adorable, that is.
