Scarriest moment in my house was when Remus descovered why going on top of the rat cage was a really STUPID idea. RB Cleo Rat was SLEEPING on the top level of the cage and remus had to jump on top for a good sniff. Cleo woke up frightened and grabbed Remus' paw THROUGH the cage and bit it hard. Remus jumpped about a foot in the air and ran off into hiding, bleeding from his foot the whole way. Blood got everywhere before we could catch him. Lucklily we got the bleeding to stop and kept it clean so no infection. He had a hard time walking for a few days because the rat bit him on the pad of his foot. He's never gone near the rats cages ever since though
