I would have to say my Ripley is not the sharpest knife in the drawer either. He's a bit strange sometimes and I also have had to deal with years of what one vet called "Feline Rage" which is directed solely at me. I've had him since age 7 weeks and I'm pretty sure there was no abuse before that.

On the other hand he is my only cat that can open door by turning door knobs. I guess he's fairly bright in some areas. Of course that may be because he's the only one big enough to reach the knobs.

He was my first cat ever and his 'behavior' almost put me off cats forever. Thank goodness my little Jazzy girl taught me differently.
