Performing Cats.

Cats, unlike dogs, are not amused by, nor do they in any way take an interest in what are termed "tricks." Performing dogs will sit about their master watching anxiously for their turn, and they have been known on more than one occasion to slip before the dog that has next jump through the hoop or over a stick, barking merrily, exulting in having excelled the other; generally they await with intense eagerness the agility of the others and strenuously try to surpass them. Possibly this is so from the long time the dog has been under the dominion of man, and taught by him how to be of service, either in hunting, sporting, shepherding, watching; in a sense his friend, though more his bond or slave, even to dragging carts, waggons, and sleighs, to fetch and carry, even to smuggle. Long teaching, persistent teaching from time immemorial has undoubtedly had its due effect, and in some instances, if not all, has been transmitted, such as in the pointer and setter, which particular sections have been known to require little or no present training, taking to their duties naturally, receiving but little guidance as to how much, when, and where such instinctive qualities are required.
