You can tell a cat's mood by looking into its eyes. A frightened or excited cat will have large, round pupils. An angry cat will have narrow pupils. The pupil size is related as much to the cat's emotions as to the degree of light. Ear furnishings are the hairs that grow inside a cat's ears.
Cats have true fur, meaning that they have both an undercoat and an outer coat.
Newborn kittens have closed ear canals that don't begin to open for nine days. Cats with white fur and skin on their ears are very prone to sunburn. The way you treat a kitten in the early stages of its life will effect its personality traits in its adult life. Cats must have some fat in their diet because they can't produce it on their own. Cats have AB blood groups just like people.
