I couldn't pick a favourite if I tried. They all have such different personalities. Lucy I love because she is placid and so ladylike. Moose is a bit shy but a real gentleman. Alvin is the boss, very curious and loving too, he loves to kiss me. Bella and May are like two peas in a pod, they are from different families but so much alike. They are so naughty and mischievous (in a good way) and so very playful. Bella loves to explore while May is more of a careful one and a follower.
What can you do with rats or what do they do with you? I remember my elementary school teacher had a pet rat. She brought it to school and just had it in the room without a cage or anything. Are rats loyal? Where do you get them?
