Rat safety is actually very important in the BHA, and any report of abuse and/or mistreatment of rats is promptly investigated, and any club found guilty of such is immediately and permanently banned from the organization.
The rats are generally owned by either the judge or rat wrangler, and are used to being handled, and the tubes are designed to be as safe as possible for both rats and dogs.
Thanks for the added information. I really wasn't that worried. I've seen and heard of their protection. Guess I took a misstep on trying to make a funny. I apologize.
