When I was a little boy, my family had a himalahin mix named Blue, who later died at 16 from kiddey failure, too much low quality food throughout his life,.http://www.thecatsite.com/forums/ima...es/bawling.gif. He was one smart cat! My dad told me he could open doors by jumping up on the oppsite knob and jarring the surface, then walking in.http://www.thecatsite.com/forums/ima...ilies/EEK2.GIF curious ever have a cat do this?
