Whether you have one rabbit or ten rabbits and are not planning on breeding from them, we would recommend neutering at a relatively young age.
It is beneficial for both behaviour and physical health throughout their life. Uterine cancer in middle-aged female rabbits that haven’t been speyed is very common.
Castration for male rabbits (bucks). Speying for female rabbits (does).
We generally recommend:
Castration at approximately 5 months.
Speying at approximately 5 months.
