Rad has dangerous glue lines

I bought this bike for my golden hamsters in a pet shop and was initially confident that we have done the right thing for my pet. The golden hamster ran and ran ... to literally bled his paws. This is probably due to the fact that the surface of this wheel very rough and also with (as I discovered in hindsight) edged glue lines is provided. The bike I could exchange for free and now I have one appointed by Rodipet, where work is done only with soft cork. Karlie's products, I will probably not soon buy.
