grr. my cat is 17/18 kind of vague on that but we got him about the same time we 'got' my little sister. he is so old and i think he's senile. he stands in the kitty litter and pees outside the box. dude the ad says think outside the box not pee outside it! ok so i'm finally caught up on the sleep i lost tues and wed. slept for like 12 hours straight. woken up feeling a little yawny but dude i'm no longer part of the angry dead walking. its nice
