I finally opened the run for one of my males, Big Boy this week. He is a pretty good sized standard male and was having trouble making it into the run... and then back into his cage. I wanted to share a picture of his big behind peeping at me through his hole.
He gets into the run by jumping and darting in quickly.. struggling to get his back end through all the way. Getting out is another story.
he's getting used to it again. These girls will most likely help him to shed a little weight and make it easier on him.
