They do not have periods, exactly; rather, they go into heat. In humans, menstruation is believed to be a "womb cleaning" that occurs at the opposite end of the roughly-monthly menstrual cycle from the fertile times. In dogs and cats, the equivalent clean-out seems to happen immediately before and as the animal becomes fertile. A little blood spotting is quite common, especially in dogs, as a dog "comes into heat" or enters her fertile period. Cats seem to be more fastidious and leave little sign of spotting.
