I concur with Ser. Rats are intelligent and affectionate and pretty easy to take care of. I had a friend who used to give her rat free range of the house and he would come when you whistled. And they come in a variety of coats and colors. Rex rats have curly hair, hooded rats are like Astrid and have hoods. One of the things I like best about them is they like to snuggle. And they're really clean, they constantly groom themselves.
