This also minimizes damage caused from a fall to their limbs and internal organs. Cats have a bony structure in their penis called a baculum. They also have sharp backwards facing barbs on their penis as well. These are used to stimulate ovulation, as female cats are induced ovulators, meaning they will not ovulate before mating. This, coupled with the fact that more than one egg is released at a time and at different times, means that kittens or cubs in a litter can have different fathers.
Cats communicate in a variety of ways, from scent to visual to vocal.
Cats will regularly mark off their territory with urine. Small cats bury their feces, large cats do not. Also, some male cats do not bury their feces, and use this as territorial markers. Cats also use a substance secreted from the anal glands to mark. Scent glands are located on the chin and paw pads, and are used to mark.
