Fully anecdotal, but got into a conversation with an animal trainer once after a demonstration that he put on. After mentioning how impressive the training of the cats in particular he said he actually preferred working with them and got more accomplished in his training sessions with them. Said they were much more "business-like" and weren't distracted by everything like dogs are.
