Oslo's favorite thing is my christmas slipper. It is a reindeer with bells on the end of the antlers, and it is bigger than him! He runs up to it and pounces on it to hear the bells, once he jumped inside it! I also bought him a chewwy "rattle" and he plays with it all the time, throwing it in the air, gnawing on the "carrots" etc. I just love watching my bunny have fun!
