Ever seen a Maine Coon? The large body structure of that breed might be the cat you need. With all four paws on the ground you should be well balanced to reach the top shelf.
Well, I'm not sure how sturdy a cat is going to be in the situation. You might want to try a big dog if you need to stand on something sturdy.
Yeti Bucket winner was chosen. Bucket with lid enroute. Also enroute is a Yeti mug with the Expat Knives logo on it and the guy's name. Thanks for all who played. He won about twice his money back in Yeti swag. New contest coming soon.....
