No, because it is not something that can easily be proven. I have read and heard enough about the subject to believe that I came to a logical conclusion.Again, do you have any proof to back that up, along with linking it to parents buying them because kids saw them at zoos?
Young children who want a rabbit or guinea pig as a pet will obviously always want one for a reason. Said children seeing domestic rabbits and guinea pigs at a zoo and thinking that they are cute is a conceivable reason for them wanting one.
