Guinea pigs are rodents and become sexually mature very early. It is recommended that the different sexes be separated from 3 weeks of age until after desexing. Females can become fertile from 4-6 weeks and males from 9-10 weeks. Females over 8 months old who become pregnant for the first time often have great difficulty giving birth as their pelvises close and a caesarian surgery may be needed.

We strongly recommend desexing your guinea pig to help avoid:

• Unwanted pregnancies
• Uterine disease
• Testicular disease
• Rectal disease in entire males
• Behavioural issues such as fighting
• Ovarian cysts – These are extremely common in older entire females. They can become very large and painful, and occasionally are hormonally active, causing hair loss and other diseases.

Desexing your Guniea Pig may seem daunting. The Rabbit Doctors, do everything possible to make the surgical anesthetic and recovery is as smooth as possible.

Before your Piggie has surgery - Pre-surgery consult

One of our vets will have a consultation with you. It is important to check your guinea pig is healthy and well for surgery. They will then walk you through the procedure and will happily answer any questions and concerns you might have.  

Day of the surgery - Drop off

You and your piggie will arrive at the clinic the morning of their procedure.  

Your piggie should have food and water right up to their surgery- no fasting is required!  

After their surgery - discharge & pick up

Your piggie will be ready for collection that same afternoon. When you come and collect them, you’ll be given full instructions on post-operative care and pain relief and any other special requirements your bunny might need.

One Week later - Post-op check

A week after your guinea pig’s operation, you will have a post-op check. This is to make sure your piggies' wounds are healing properly. This appointment is free of charge and is often done with a nurse.

Your piggie will be a little quiet that evening but are usually back to their cheeky selves after 24-48 hours.
