Guinea Pig Bedding Calculator – How Much Bedding Per Month

Bedding seems simple until you are in the shop trying to guess how many bags you need. Buy too little and the cage floor goes bare before the month ends. Buy too much and heavy bags sit in a cupboard for months. This free bedding calculator turns your cage area, bedding depth, and change frequency into litres per change, litres per month, kilos per month, and bags per month, so shopping becomes a number, not a guess.

Bedding does more than cover the floor. It soaks up urine, controls smell, gives grip for little feet, and lets pigs dig and nest, which is natural behaviour worth supporting. Paper based bedding, wood shavings, and hemp all work, but they differ in dust, absorbency, and cost. Fleece liners are a separate system with washing instead of buying, and this calculator covers loose bedding, not fleece.

Using the calculator is quick. Enter the cage floor area in square metres, the bedding depth in centimetres, and how many full changes you do per month. Press Calculate bedding and the result shows litres per change, litres per month, approximate kilos per month, and how many twenty litre bags that means. A cage of one square metre at five centimetres deep needs fifty litres per change.

A worked example shows the monthly maths. One square metre at five centimetres deep is fifty litres per change, and with four full changes per month that is two hundred litres per month. At about nought point one two kilos per litre, that is about twenty four kilos per month, or ten twenty litre bags. Spot cleaning daily and doing two full changes instead of four can cut that roughly in half.

Depth matters more than most owners expect. Less than three centimetres soaks through fast, smells sooner, and leaves wet patches that irritate feet. Five centimetres suits most loose beddings, while deeper beds of seven centimetres or more suit diggers and help in larger cages. Do not go deep with dusty shavings, since dust rises every time pigs move, and dusty bedding irritates lungs over time.

Spot cleaning is the habit that saves the most bedding. Scoop wet patches and soiled corners daily, replace just that bedding, and the full change stretches much further. Keep a small scoop and a bag by the cage so the job takes two minutes. Full changes still matter weekly or so, because smell builds in the base layer even when the surface looks clean.

Choose bedding by dust and safety first, and price second. Dust extracted paper or hemp suits most pigs, while cedar shavings should be avoided because the oils irritate lungs. Aspen shavings are safer than pine, but dust extracted paper beats both for sensitive pigs. Store bags dry and sealed, since damp bedding grows mould fast, and mouldy bedding should be thrown away, not used.

Buying in bulk saves money only when storage stays dry, so check your storage before ordering a month of bedding at once. A damp garage or a leaking shed ruins paper bedding fast, and mouldy bedding is worse than no bedding at all. Order two weeks at a time until you know your monthly use from this calculator, then move to monthly orders once the number proves stable. Keep one unopened bag in reserve at all times, so a late delivery never leaves the cage bare. Track actual bags used for two months against the calculator estimate, and adjust the change frequency in the tool until the estimate matches reality, since your pigs, your cage, and your cleaning routine are unique to your home. Keep the scoop clean too.
