My 14- or 15-year-old, long-neutered male cat got an erection just now. Actually, it was more like a nub, but it was definitely an engorgement of the erectile tissue. I, uh, didn’t know that could happen, though I suppose there’s nothing about the surgical removal of testicles that prevents it. I just thought that neutering sort of, well, removed the impulse.
Weird. Also weird that he wouldn’t stop licking the damn thing. Erk.
