The differences as regards affection for localities which is shown by cats and dogs are perhaps to be accounted for by an original and essential variation in the habits of life in their wild ancestors. Judging by the kindred of the species which are known to us in their wild state, we may fairly suppose that the dogs were of old accustomed to range over a wide field, having no fixed place of abode; the pack ranging, if the occasion served, for hundreds of miles in any direction. On the other hand, with the cats, it is characteristic of the species that they have lairs to which they resort, and a definite hunting ground in which they seek their food. They are, in a word, animals of very determined routine. As there has been no effort by breeding to change this feature, it has remained in all its old ingrained intensity. As a consequence of the affection which cats have for particular places, they often return to the wilderness when by chance the homes in which they have been reared are abandoned. Thus in New England, in those sections of the district where many farmsteads have of late years been deserted, the cats have remained about their ancient haunts and have become entirely wild. In this State they are bred in such numbers that their presence is now a serious menace to the birds and other weaker creatures of the country. The behavior of these feralized animals differs somewhat from that of creatures which have never been tamed. They have not the same immediate fear of a man, but the least effort to approach them leads to their hasty flight. While considering the inelastic quality which is exhibited by cats as compared with the dog, the naturalist notes with interest the fact that the former creature belongs to a family which has never been accustomed to any social life beyond the limits of the family. Moreover, all the cats have the habit of hunting in a solitary way, each for itself, in the achievement and in the result. It is otherwise with dogs. They belong to a group which hunts in packs. For ages they have been used to a communal life. Their minds have thus become accustomed to social intercourse; they are used to having their excitements of the chase in comradeship, and generally they are accustomed to the rough-and-tumble fraternity which we behold in a pack of wolves. It was long ago remarked that the really social animals are those which afford the only good material for subjugation. The difference between the cat and dog seems, in a way, to warrant this statement.
