WIP!! Idea dump: Cave diggers Tail brush Teeth strong enough to crush diamonds Different teeth ranks (labeled as gemstones) Thick fur prevents dirt Claws only can dig dirt Folded ear side effects :( Sickness Lack of Sight In depth: Cave Diggers - These cats love digging! It is their society, their food source, and even their religion! If they get mixed up into a different clan, they tend to wind up back to the caves, due to harsh living conditions outside of it. Tail Brush - Their tail, as shown in the example, tends to sorta be in the shape of an axe(?) I'm not sure what that would be called lol. It is very shaggy, and the fur falls very easily. They use this to wipe away dirt from their dig sites, so they can see the gemstones easily. Strong Teeth - Their culture surrounds the fact of how strong they can chop through things. This would be genetic, and would be specified on any litters that the cat would potentially have. Before the cats were civilized and cultured, the teeth were used to attract mates. Thick Fur - Their fur is highly thick to keep out any dirt. They can use their chest fur to breathe in the tunnel clearly, although breathing not in their chest is fine for a bit, but not in the long run. (see: Dirt Lung) Teeth - Unlike their teeth, their claws can only dig through dirt. Anything else will cause them to tear. Folded ears - Though good for keeping dirt out, it will keep dirt in. The cat themself cannot clean them, so it is a tradition of the clan to clean out each other's ears. Otherwise, the ears do not effect the cats. Sickness - Dirt Lung: Major illness. 5% chance to get after every mining expedition. Even when fully healed, there will always have side effects of a rasp and 10% chance every following hunts. Ear Infections: Minor Illness. 2% chance to get per moon or each cat. Easily curable. Lack of Sight - These cats commonly have poor eyesight, due to not needing it at all in the caves. They are sensitive to light however, and can see gemstones easily.
