Well when your chins breaks a leg, gets a head injury from the cross bars or a back injury from running on that wheel at that angle, then maybe you will actually learn. To me, if I was told something was unsafe and why it would be gone from the cage, period. Your attitude is really amazing. You claim to be here to learn, you are told a wheel is unsafe, you are told not to breed chins from unknown backgrounds because of genetic issues that can be present and not expressed, you claim to have all these great chins from all these great places yet insist you want to breed this rescue chin when you obviously know how to buy chins from the correct places, so what about ignoring that info is learning.
