This is my gerbil Kesha. She is my nice one. The other one (Kia ) bites. They are only calm when A: they are sleeping or B: they have a nut. (by Isaac)

These gerbils are fun to watch.  Kesha will take a nut while being held but Kia is too up tight.  This is the longest we've had a rodent, not to mention two rodents.  I've been impressed with Isaac.  Every morning he feeds his gerbils some nuts and gerbil food.  He keeps track of the days and makes sure that he changes their water every two to three days.  Isaac has a stash of wrapping paper tubes and throws one in when the last one has been chewed through.  It's a good age to have a pet.
