Every cat that comes to a new area in London, appears to me to be obliged to fight till he gains undisturbed possession of it; at least so it has been the case with my cats. A very fine, bold, powerful tabby, did this twice with perfect success; but after repeated combats, although victorious, the struggle made him fierce and occasionally sullen. Another who was a very beautiful creature, but much weaker, used to come in with his handsome ears slit, his cheeks swollen, his fur torn off, his frolic and vivacity gone; and he sat crouching by the fire all day. At night he was roused by the fierce defiance of his enemies; and the contest continued till he died from his exertions. One cat belonging to me had a curious manner of shewing her disappointment or anger, whichever it might be; for the instant she was affronted, she walked away and seated herself with her back to the offending parties. A child of hers was an instance of the effect of judicious education, for fair and gentle treatment transformed her, from a violent, outrageous kitten, to a well behaved cat, and it was curious to see the instantaneous effect which the voice of his preceptress produced. Cats will learn all sorts of antics, and form all sorts of contradictory attachments; young birds, puppies, rats and mice frequently being the objects. My mother-in-law had both a favourite canary and an equally beloved cat; the former lived in her bed room; and when alone, she suffered him to fly about the room, for she could there exclude the latter. Chance, however, discovered that puss was as fond of the canary as she was; and, to her surprise, on raising her head from her work one morning, she saw the bird perched upon the cat's body, without fear, and the cat evidently delighted. After that there was no further restraint, and the two pets were daily companions. Their mistress, however, received another fright; for Puss gave a slight growl, and seizing the bird in her mouth, leaped on to the bed; her tail swelled out, her hair erect, and her eyes as big as four. The bird was of course given up for lost: but the door being accidentally left open, a strange cat had come in; and it was for the preservation of the bird, that the cat had seized him, and as soon as the intruder was driven away, she set the prisoner at liberty. Cats have often been trained to act as game-finders, without offering the slightest damage to their capture; they have given the alarm when thieves have been breaking in; and manifested great proofs of reflection and thought, which may be called reason, without degrading this act of the intellect. One belonging to my sister invariably goes to her room when she rings her bell; but does not offer to stir when any other bell in the house is sounded. Another, in the service of a friend, was in the habit of going into the garden, catching a bird, and bringing it to the cook, appearing to ask her to dress it; and yet it was perfectly her own suggestion.
