Gray lop-eared rabbit with blue collar

Yesterday around 3pm I lost my small gray lop-eared rabbit. It slipped out of my apartment door when I opened it to bring out trash, and I last saw it near the Angelo State University campus along North Bryant Blvd, by the campus green behind the Student Center. The rabbit is about the size of a loaf of bread, with soft gray fur and a white belly. It wears a bright blue collar with a tiny silver bell, and there is a small white heart shaped patch of fur on its chest. One ear tends to flop more than the other. This little guy is a gift from my kid and has sentimental value; I really need to get him back. If found, please email me at [email protected].
