Preparing your guinea pigs’ home
What size hutch do guinea pigs need?
The more guinea pigs you have, the bigger the hutch you’ll need. The absolute minimum floor space required for one female is 1200cm2 with a wall. A floor space of three to four times this is recommended if breeding guinea pigs.
Ask your local Petbarn team members for advice on the perfect enclosure.
Where should you place a guinea pig hutch?
Place the enclosure out of reach of other animals and out of any areas exposed to draughts and direct sunlight.
Provide adequate heat protection as guinea pigs are susceptible to heat stress. Avoid exposing guinea pigs to temperatures above 25°C for long periods of time and take steps to keep them cool in summer. These pets will thrive in temperatures ranging from 18–25°C.
What do you put on the bottom of a guinea pig hutch?
Line the hutch with newspaper covered with soft bedding like straw, wood shavings, or recycled paper.
What items do you need to put in a guinea pig hutch?
Hang a drink bottle on the outside of the enclosure with the spout pointing inside. A heavy food bowl is necessary, as is a hidey hut and toys.
What’s the best way for guinea pigs to drink water?
A guinea pig needs about 100ml of water per day, and it’s important to change their water daily. We suggest using a hanging water dispenser, as water bowls can be messy and are often tipped over. It’s best to refresh your guinea pig’s water every morning, but keep an eye on their water during hot days.
How often should you clean a guinea pig cage?
Spot clean your guinea pigs’ cage daily and do a thorough clean every two to three days. Replace the bedding, wipe down the cage with hot water and wash the elements, such as toys and drink bottles, with a guinea pig-safe disinfectant.
You’ll need a substitute home for your guinea pigs while you clean – a travel cage is perfect.

Feeding your guinea pigs
What do guinea pigs eat?
Guinea pig nutrition is a bit different to other pets like dogs and cats. The main part of your guinea pigs diet should be hay. For these herbivores, chewing hay is important to stop their teeth from growing too long in addition to nutrition.
Guinea pigs also love to munch on veggies like broccoli, cabbage and celery, as well as herbs like mint, parsley, and coriander. Keep in mind that you should throw out any fruit and vegetables that have been in their hutch for more than 24 hours.
You can also give guinea pig pellets, which you can find at your local Petbarn. These should only supplement other items on the menu, and not be the main basis of their diet.
Guinea pigs are unable to make their own vitamin C. While some vegetables contain vitamin C, you will need to provide your pets with a suitable supplement to keep them healthy.
If harvesting plants from your backyard to feed to your guinea pigs, ensure they are free of pesticides, as these chemicals can be harmful to your pet.
What foods are bad for guinea pigs?
Do NOT feed your guinea pig:
- Grains
- Cereals
- Nuts
- Lawn clippings
- Rhubarb leaves
- Pink clover
- Hemlock
- Chocolate
- Caffeine
- Alcohol
Avoid feeding your guinea pig grains, cereals or nuts as this may cause digestive problems.
Guinea pig-proofing your home and backyard
Let your pet guinea pig run inside or outside every so often. Get a playpen for outdoor runs.
For indoor adventures, block any small holes and ensure no other animals have access to the room. Remove electrical wires, ingestible items and toxic plants and maintain supervision at all times.
Grooming your guinea pigs
An essential part of parenting a guinea pig is grooming. Just like you, your guinea pig will need some hair maintenance every once in a while. Handling and grooming your guinea pig once a day will give you plenty of bonding time and will improve their confidence and comfort when being handled.
How to groom a guinea pig
Using a firm, soft brush – you can find suitable guinea pig grooming options at your local Petbarn – remove any excess hair, tangles, or anything else that may have been caught up in there, like twigs and leaves.
During your regular grooming routine, make sure to check your guinea pig’s skin and nails. You will need to take your guinea pig to your local Greencross Vets for a little manicure when their claws get too long.

Caring for your guinea pigs’ health
Guinea pigs are susceptible to contracting various ailments. Keep your guinea pig in good health by being proactive with preventative health. If cared for properly and taken for biannual check-ups at your local Greencross Vets, your guinea pig will be less likely to fall ill.
A few of the many guinea pig veterinary needs offered for you and your pet are: desexing for both male and female guinea pigs, parasite control, dental care, preventative medicine, nutritional and husbandry advice and supplies, and nail trimming.
What health issues are guinea pigs prone to?
Your guinea pig is vulnerable to skin ailments, fleas, vitamin C deficiency and dental problems.
How to care for your guinea pigs’ teeth
One of the key things to remember with your guinea pig is that their teeth grow constantly. If their teeth become overgrown, it can lead to serious health problems and will need to be looked at by your vet.
To help look after your guinea pigs’ teeth, feed them plenty of chew sticks and abrasive foods such as celery, broccoli, corn and husks to gnaw on and keep their teeth trim and in check.
Should you desex guinea pigs?
Desexing your guinea pig may their risk of disease, increase their lifespan, make them calmer and stop them reproducing. Your local Greencross Vets will be able to do this for your new pet.

A healthy guinea pig will be alert, active and have a shiny coat.
