Alrighty then... I know you all have been on the edge of your seats waiting for an update on this problem. LOL So I took Finny, A.K.A. "Earthquake" and now "Chester", to the vets to make sure this humping problem wasn't hormonal or anything disease wise. Boy was this an embarrassing talk! Anyway, so it turns out that other than being super huge, Finny is healthy but this much "activity" isn't normal for any cat. Vet said he was asserting his dominence. Now that is just funny because Fin is about as mellow as they come. He licks everything... dogs, cats, lizards, shower, tubs, leaves, carpet, walls, anything electronic... he couldn't be more of mellow, fatherly type cat. Pretty much cleans every stray cut that comes around. Loved by our neighbors, loved by groomers, loved by assistants.
Diagnosis.... I have a horny cat.
