Hi Everyone, was hoping for some advice. We have had our rabbit for about a year now and have tried to build him a little runaround system with a tunnel connecting his extended run. The problem is, he just does not go into the tunnel. We have tried leaving bits of food in there to entice him, but he pays no attention to it at all - not really sure he knows its there. Has anyone else had this problem? before we got him, we think he was not let out of a pretty small hutch so much, so guess he has not done this kind of thing before and maybe has lost a little of his exploratory nature. He is almost 6 now. Really want him to have constant access though, so any advice is appreciated. Thanks so much!
