ALWAYS neuter and spay your rabbits. If you don’t you will have far too many babies – and there are too many rabbits needing homes already. Un-neutered male rabbits bonk you or sexually harass their companions. Unspayed females get womb cancer and die early. So neuter and spay, just like you would a cat or a dog. If your vet advises against this, find one that understands rabbits.
