That looks exactly like the type of form letter the regional reps would ask them to send out. It may or may not have even happened. There have been instances people giving away pets and finding out later the new owner did something unhappy with them but I have never heard of anyone actually hoarding them.
I specifically exclude all animals on my list just to avoid the possibility of having to deal with that. Ironically, of the problem members I've had, most have been idiots who got abusive when I told them no animal posts. There's just no winning on that topic.
Besides - who is going to put their pet in a landfill, anyway?
