Heather....
So what I really mean to write in the above email was that perhaps you should write a follow-up letter to the pet store that had the boys mistreating the bunnies. It can't hurt and it shows that you have NOT forgotten the incident and are "watching" them. A polite letter with a request for a reply certainly can't hurt and other animals in that store might be spared a similar or worse experience. Just a suggestion.....
