Well, with the "evil eyes" in the photo of Nilla, I should have seen it coming....yup, he did it again, he attacked and attacked only this time we were at my parents' house. Dad and I tried to capture him to get him to the vet, but we couldn't get it done We finally called "the mobile vet" who came out. We trapped him in the den, and he literally ran up the walls- that was an amazing sight- we got him in a net, tranquilized him and he's now spending the night at the local vet.
This isn't good news. We can't figure out what triggers it. He's either having some sort of psychological break or he's got a brain tumor or something. Anyway, I'll know more tomorrow. I can't live with a cat who just freaks out and attacks me for some unknown reason.
