Neutering your guinea pig: what you need to know

Guinea pigs are sociable animals – they should always be kept in pairs or small groups to keep them happy and healthy.

The best mixes are two males, two females or a neutered male with one or more females.

In most cases, only male guinea pigs are neutered. Neutering female guinea pigs can be very risky and should only be taken on by a guinea pig savvy vet if it needs doing for emergency reasons.

Unlike rabbits, neutering male guinea pigs doesn’t affect their behaviour and will not reduce fighting between a pair. Therefore, the general advice is to only neuter male guinea pigs if they cannot be paired with a male due to fighting, and need to be paired with a female.

Male guinea pigs can be neutered from 3-4 months or as soon as their testicles are visible.


Before and after care for your guinea pigs

Some small animal species need to be starved for a certain amount of time before an operation, guinea pigs should not be starved, and must have a constant access to fresh hay and water.

Once your guinea pigs have returned from the vets, it is very important to monitor their castrate wound for swelling or signs of infection. You should also monitor their toileting output which should be of normal amounts – if this has reduced or the poo appears smaller, then it is important to take advice from your vets straight away.

It is very important that a male is neutered and rested for up to three weeks before you pair with a female to prevent unwanted babies.
