Choosing Bedding for Guinea Pigs

What bedding needs to do

Bedding should absorb urine, provide a good cushion and be easy to replace before it gets wet or dirty. It has to be compatible with your enclosure and your cleaning regime. A cheap material that just sits wet and requires you to wash it far more often than you're prepared to do is not going to be a good fit.

Guinea pigs spend their lives right down near the floor so check the bedding at animal level (under the hides, around the water etc). The top may look perfectly clean while moisture has collected underneath. A strong smell is no substitute for removing the waste.

Compare bedding systems rather than packaging

Choose the cleaning you can do yourself, the animals' comfort and your own home laundry or waste arrangements. Neither paper nor fleece will stay hygienic without a daily regime. A reusable liner will reduce the amount of disposables but will of course add to the washing and drying. Disposable bedding still requires storage and will need to be replaced on a regular basis.

Some keepers combine washable main flooring with a disposable-bedding hay area. If you try this, make the transition level and easy to cross, and keep both areas clean. It is an optional arrangement, not a requirement or a reason to reduce usable floor space.

For wood-based materials don't treat "wood shavings" as a single entity. RSPCA would advise against the use of softwood products (i.e. pine). Avoid cedar, strong fragrance and dusty bedding. If in any doubt choose a clearly appropriate low dust alternative. Don't use fluffy cotton-like nesting fibres, exposed wire floors or straw as a substitute for edible grass hay.

Understand what each fleece layer does

A purpose made liner can have layers, a loose fleece blanket cannot. Always follow the care instructions for the actual material. Prior to first use, wash as per the instructions and do a test with a little clean water on the fully prepared liner. It should pass through rather than bead. Dry the test area prior to putting the liner into use.

Don't leave any absorbent pads, loose backing or plastic liners where they can be chewed. Fit the system securely so that there are no loose threads or folds which would trap a foot. Check the corners and any sheltered areas as well as the middle of the floor that is visible.

Choose a setup you can maintain on a busy day

1. Cover the entire usable floor and the routes between feeding and resting areas.

2. Keep a completely clean, dry spare set before you start using the fleece.

3. Put in the replaceable pads at the obvious wet areas (without of course blocking access or creating any loose edges).

4. Keep the same layout but change the bedding so the animals aren't presented with every single feature changing all at once.

Rehearse a full change with the enclosure empty. Where will the animals wait safely? Where will the used bedding go and how will the base dry? A secure temporary area will still require appropriate shelter and access to both hay and water. You'll need cleaning materials on hand so the animals aren't left waiting around whilst you go hunting for a spare liner.

For paper bedding you want to buy enough to properly replace the wet areas rather than trying to stretch the supply by just putting a thin layer of clean bedding over the damp patches. With fleece you need to check that your clean spare actually fits after washing and drying. It's easy for it to shrink or bunch up and leave the floor exposed.

Use a repeatable fleece washing workflow

1. Remove the hay, droppings and loose hair before loading the machine. Keep this waste well away from food prep areas.

2. Check the seams, the corners and the backing. Any damaged material goes in the bin rather than having a loose thread simply covered and put back in the cage.

3. Wash with an unscented detergent and the cycle that is permitted by the liner's care label. Don't overload the drum.

4. Don't use any fabric softener or dryer sheets as these can actually interfere with wicking. Just follow the rinse instructions for the material in question as detergent residue should not be left behind.

5. Dry completely using the method specified in the care label. You'll be able to feel the thicker seams and backing rather than just the top surface.

6. Check the fit and wicking when required and then store the clean, dry set separately from the used bedding.

There's no one wash temperature or dry method that will work for all liners. You have to follow the instructions for the particular fabric and machine. The manufacturer's care guide that's linked to this is a guide to the general principles of washing, it's not a recommendation to buy that particular brand. Routine laundry is not the same as a vet level disinfection protocol.

If an animal has a contagious condition then ask the vet what you should do with the bedding, the equipment and the laundry. Don't go off and invent your own chemical mixtures, don't rely on vinegar as a disinfectant. Never mix cleaning agents.

Plan daily checks and regular full cleaning

RSPCA recommend daily spot cleaning and on average a full clean at least once a week. Use that as your baseline and then clean sooner if the bedding is wet, dirty or saturated. The number of animals, the layout of the enclosure, any leaks and the type of material all have an effect on how quickly a particular area will need cleaning.

If the animals are healthy and there is no infection-control instruction, keep the layout familiar through cleaning. Fresh bedding should not mean removing every shelter at once. Return equipment securely and confirm water is flowing after reassembly.

Find the cause of recurring wet patches

Write down where the wet patch occurs and how soon it returns. A simple sketch helps you distinguish a leaking drinking point from a heavily used resting corner. Change one part of the system at a time so you can tell whether the adjustment helped.

Keep a dry-floor checklist beside the supplies

Track a week of actual material use or laundry loads before comparing costs. A useful record is: date, areas changed, full liner or paper quantity used, and any recurring wet spot. It lets you judge the system in your own enclosure rather than relying on an advertised lifespan.

The cage layout guide helps keep cleaning access practical, and the food guide includes a matching daily feeding checklist.
