I'm surprised they're only £10 tbh. They relly ought to raise the price. It won't guarantee they'll go to a good home but it'd help. If they aren't spayed I could see someone taking them and using them as breeding machines, thinking they can churn out litter after litter of 'unusual' rabbits to sell.
Man, I'd love a trio of belgian hares as well... hopefully some rabbit savvy person like us has snatched them up!
