Bert is approx. 3 1/2 years old.  He came to us with his cagemate in summer of 2005.  These two were moved to 5 homes in two weeks time prior to coming here.  Bert has biting issues that we have never been able to break.  He is very playful, but at times he is also very moody.  When he and his friend came to us, their fur felt like brillo pads. Upon reviewing their health assessment forms, we found that their diet consisted mainly of fruits and veggies.  Bert is quite the little monkey.  When he gets scolded for getting into trouble, he likes to plot a revenge!  He definately keeps us on our toes!
