I bought one of these recently to try as a travel cage at the Milwaukee show. What do you mean the bottom is not solid? The one I purchased the top, bottom and back are all made of solid polyester. The sides are mostly mesh and the front door is a mesh. The one I purchased is a size Large and has just under 6 square feet of space. Its quite roomy for a hedgehog. I, however, cannot see using one of these for a dog. They are light weight and I can see a dog easily tipping them, carrying them around, or chewing them up.
As a travel cage I think they may actually be just fine for the right hedgehog. Not all hedgehogs have the same personalities though. But I will report more as my experiment proceeds. I intend to try it out on Rose this weekend as a play pen to see how she reacts in it. I suspect based on her personality she won't care as long as she has her sleeping blanket, wheel and food.
