Never, ever, ever hit, spank or tap with one finger! I cannot stress that enough. To do so will cause your bunny to start a biting habit in self-defense. Instead of physical discipline, use verbal reprimands such as “EEK!” or “NO!”
The best thing a rabbit owner can do for their rabbit and themselves is be responsible and have their rabbit spayed or neutered. This will prevent future pains, especially if more than one rabbit is owned. Unneutered males will fight each other, and spray everything in sight, and unneutured male and female will do the inevitable: breed. The best thing to do is leave the breeding up to the breeders.
Thank you for deciding to rise up to the responsibility (and rewards) of owning a rabbit. The compensation is tremendous, not as monetary value, but as a creature that loves you in return for your love.
