Neutering is the process of removing reproductive organs in both male and female rabbits. Vets and rabbit experts tend to agree that pet rabbits should be neutered, where possible rabbits should undergo the procedure before they reach the age of six months.
Does (female rabbits) can be neutered from 15 - 16 weeks of age, while bucks (male rabbits) can undergo the procedure as soon as their testicles have descended which is typically 10-12 weeks of age. It's important to remember that male rabbits can remain fertile for four weeks after the operation, so should not be kept with an un-neutered female rabbit during this time or you may get more than you bargained for!
There are numerous advantages to neutering your rabbit - the obvious being that it prevents unwanted pregnancy, saving you the trouble of finding good homes for the new arrivals. It also prevents sexual aggression in both female and male bunnies, which otherwise can be quite fierce. Studies have proved that neutering can also help to protect does against uterine cancer.
The main negative point is that, like any surgical procedure, it can be risky for rabbits, although with advancements in anaesthetic; operations today are far safer than ever before. It also results in a slower metabolism, which can lead to obesity, although this can be managed with a calorie-controlled food such as Excel Light.
