Good piece! Rats are really cool. You could say they are like a mini dog, but smarter and as clean as a cat. I had a couple and they all have a unique character and traits, they are amazing. I took one of mine illegally over 15 borders, so i imagine he was one of the best traveled rats ever. :) He used to guard me when i was sleeping and wake me up if something was up, either by making noise or even scratching or biting me... Awesome critters.
