This is what Sims 4 is lacking

SaveState - DLC has furries. You can create a dog, fox, wolf, cheetah, tiger. There's also a neon green for an alien furry. They have dog, cat or curled tails, rounded, folded or pointed ears. You can choose between hind paws or the Maxis feet and shoes. You can change the length and width of the muzzle and the size of the nose. There's an extra skin pack for more colors to use with version 2. They will keep their shape in the shower and bath. They will not change to normal Sims like a werewolf.

You would click on the head, then choose in the skin details for the head, ears, tail, hind paws. You must use SaveState's eyes for version 1. You can use the Maxis hair or crest. The long pants and some skirts can mess up the hind paws.
