Cats have fat fleshy pads at the bottom of their toes, so they walk silently. They will not startle mice when catching them. They have sharp nails on their toes. Claws can be indented and extended. Cats draw in their PAWS when they are resting and walking, and only extend them when they are catching mice and climbing, to prevent their nails from being blunted. Cats have five fingers on their forelimbs and four on their hind limbs. Cat teeth are divided into incisors, canines, and molars. Canine teeth are particularly well developed, sharp as a cone, and suitable for killing caught rodents. Molars have sharp protrusions on the chewing surface, which are suitable for crushing meat. Underdeveloped incisors.
