Domestic Cats are valued by humanoids for companionship and their ability to kill small rodents. The cat has a strong flexible body, quick reflexes, sharp teeth, and retractable claws adapted to killing small prey like mice and rats. Its night vision and sense of smell are well developed further perfecting this night time solitary hunter. It is also quite a social creature getting along just fine with other animals including those of its own kind or humanoids in general.
