The Rats/Secrets of NIMH RP discussion

Hello. I’m completely new here.
My character is Timothy Blacktip, a dark furred mouse with a black tip to his tail, and a black stripe from his nose to the back of his head. He wears a white shirt, and light brown waistcoat. He works as a sort of detective, investigating disappearances and mysteries.
I was thinking that his house would be in a tree, as he’s a wood mouse.
Also, he wasn’t an original mouse at NIMH, but he was one caught afterwards, and he received the intelligence boosting injections, but escaped one night as he grew too thin due to stress, and managed to squeeze through the cage bars.
