Well Peach appears none the worse for wear this morning. He's looking much fluffier and eating well. Not shaking his head so I don't think water got in?
As for advertising, he's on petfinder. I would point out that this is Quebec and bunnies are a definite table snack to many individuals so putting flyers up may not be a good idea for Peach. I use the theory that if someone were a responsible pet owner they would search petfinder for a bunny? I was thinking when the school year starts that perhaps a teacher would like him in their classroom as a pet and that I would keep him here for summers. He's very affectionate and likes children so we'll see.
