What happens to all the bunnies in pet shops if they don get sold?
I can say with all honesty, I don’t know. However, pet shop bunnies usually have a very short shelf life ie. they go on display at 8-10 weeks old (ideally, otherwise any younger and their survival chances aren’t good) and are classed as unappealing by 19 weeks old. If they’re not sold by that age, who knows what happens to them. Each pet shop will probably have their own answers therefore this is something I can’t comment on.
