Should I neuter my male rabbit to prevent spraying and aggression?

Updated On September 23rd, 2025

Pet's info: Other | Other Pet - Not Listed | Male | unneutered

Hello, I am currently planning on buying a male Flemish Giant kit. However, I am worried as to whether neutering is mandatory. Is it okay to leave your buck unneutered, if you are only keeping one rabbit? Are the rumours about unrestrained spraying true? Which dangers are there to not having your poor little buck neutered? Thank you very much for taking the time to consider my worries. Yours sincerely Kian Rutherford Moradchahi

Hi Kian! You have some great questions. Even when keeping just one rabbit, I don't recommend leaving a buck unneutered. When male rabbits become sexually mature, they can act aggressively. The hormones can trigger territorial and dominance aggression. The most common signs of sexual maturity in a male include circling you, mounting you, or trying to bite you. Unneutered males can also frequently spray urine. I do urge you to have Fluffy neutered before four months of age. I hope this helps!
