Black Rats

"Fast, like black lightning."

Black Rats are a rabbit-like rat, about the size of a rabbit even, that likes to live in burrows. It's fur ranges from patterns of medium to dark grey and black, or just plain black. They are fast, and are considered part of the Creatures category because they can live almost anywhere so long as there is plants and water. Their hearing is spred-out and extremely good, so sneaking up on one rarely ever works. Traps are the best way to catch Black Rats.

Is it a Black Rat?
Black Rats come in a range of grey and black, but they never have white or any colours on their fur. They have two sets of ears, the back ones are usually turned to listen to things behind it while the front takes care of the noise ahead of it. Their eyes are great in evening and night, and are yellow, brown, orange, or a mix of two or all of the three. They like to be out at night as bright lights and sunny days make it harder for them to see.

Black Rats like to hide among rabbits, so they'll put their front ears and back ears together on each side to try and look like a normal rabbit. Known for being one of the best Creatures out there for creating remedies with their immune system, they use their ability to blend in with rabbits to avoid being caught by Humans looking to test things on their bodies. They've also been known to trick rabbits by attempting to mate, and then eating the rabbit.

Trivia

 * Black Rats are easy to manipulate, so they tend to be the asses of a lot of lore.
 * Their immune systems are highly active. Subjecting them to poisons and toxins repetitively makes their blood into a makeshift antidote. Transfusing a portion of their blood into someone can cure them of infections, but doesn't help against something like progressed cancers.
 * All Black Rats have the 0+ blood type.
