It’s empty in here!
My bunny loved this once I broke it up for her. In cage, she was throwing it around to try and break it. She even put it in her water to soften it like she does with other things, but no joy.
My 5 month old dwarf rabbit went straight for this once I put it in her cage, which she is out of most of the time. It fits nicely to the wire. She is an indoor rabbit and has a plastic and wire cage to sleep, eat and toilet (in her litter tray), has she is out of the cage when I am around, which is most of the time. Would recommend and I will continue to purchase every time she needs one.
