everyone, thank you very much for your concern. our jumpy kitty is a black and white guy with very big paws. he has lovely green eyes (both are green) and a big heart! we recently took him and another cat of ours to the vet about 1.5 months ago due to some litter box issues but the vet found nothing wrong with either cat. we concluded the litter box was too small for this big ol' boy and we got a big box and the problem has been eliminated. however, we've never had his ears checked before, but we know he hears b/c he always comes when called and he always seems to hear things outside. maybe he is only sensing vibrations? not that he's a dolphin or anything.... he's barely 2 years old, possibly younger (we adopted him at the humane society so it's very much an estimate). he's grown a LOT since we got him, so we think he may have still been a baby.

either way, if you have any other thoughts please let us know. otherwise, i'll be scheduling an appt very soon!
