Like cats and dogs, routine neutering of rabbits is recommended.
Castrating males can help to calm them down, will eliminate the risk of testicular cancer and can prevent the rabbit from spraying everything, including you, with urine! We can castrate male rabbits from about 4 months of age.
Spaying females can help to reduce any aggressive and territorial behaviour. It also eliminates the risk of Uterine Cancer, which is extremely common in un-neutered female rabbits. We can spay female rabbits from 4-6 months of age.
Neutering male and female rabbits also makes litter training a lot easier and allows you to keep more than one rabbit together happily.
