The letters are sent (by Jimmy Legs)
From the description:
A lot of us have been very upset to learn about Paul Zhang and his mission to kill as many cats as he can. The story broke a week ago, but today I finally mailed out nearly 200 letters to local vets, alerting him to what he’s been doing. If you haven’t heard about it, Mr Zhang is a former TNR advocate who mysteriously did a 180 and began trapping street cats and taking them to local vets to have them put down. There’s more to the story, please check stoppaulzhang.wordpress.com/ for more info.
