So I've been noticing that Harry isn't as alert as he once was. I'd attributed this to the fact that he's the cat equivalent of eleventy-seven human years, but lately I've begun to suspect he's lost his hearing. That would explain many things, including why his meows have become deafeningly loud. (If he's not deaf, he's probably wondering what crack I've smoked that makes me sneak up behind him and yell "HARRY!" at the top of my lungs.)
His ears don't even twitch, and after I've sat right by him calling his name with no response, I'll pat him and he'll startle. So.
It makes me a little bit sad, but I'll be less angry with him for waking me up at night with his smoke-alarm yowling.
