Cats have retractile claws, slender muscular bodies and strong flexible forelimbs. They have bushy tails and large paws with partially retractile claws. Their features include retractile claws and the ringed tail. Most have retractile or partially retractile claws, a baculum. Hani and kif, as predators, also have sharp retractile claws and sharp teeth. They all have long bodies, short legs with retractile claws, and usually long tails. Many feliforms have retractile or semi-retractile claws and many are arboreal or semi-arboreal. These are highly modified into retractile tentacles, much larger than the locomotive tube feet. There are 41 extant species, and all but a few have retractile claws. They have 15-30 shield-shaped retractile tentacles surrounding their mouths. The two tentacles are much longer than the arms and are retractile. It has also been called mesenteric lipodystrophy, or retractile mesenteritis. The mouth is large, muscular, strong and retractile.
