Training Pads Under Liners: A Practical Layering System
The floor of a small-animal habitat has to do two opposing things: stay dry where the animal sits, and hold everything the animal produces. No single material does both, which is why layering works better than any one product.
Why one layer never works
Loose bedding absorbs well but scatters, gets kicked out, and has to be replaced entirely each week. Fleece is comfortable and washable but does not absorb at all — it wicks moisture through to whatever is underneath. Waterproof bases hold liquid on the surface, which is the worst outcome for the animal.
Put them in the right order and each does what it is good at.
The layer order
- Waterproof base. The habitat tray itself, or a plastic sheet over a grid floor.
- Absorbent layer. Training pads, old towels, mattress protectors or purpose-made absorbent liners. This is where the liquid ends up.
- Fleece top. Wicks moisture down into the absorbent layer and gives a dry surface to sit on.
Tuck the fleece under at the edges so no part of the absorbent layer is exposed. That tuck is the safety step, not a tidiness step.
The safety rule
Training pads contain an absorbent gel. They are not chew-safe and they are not intended to be reached, which is why the barrier matters.
If an animal gets through a gap, chews an edge or pulls up a corner, remove the pad and use towels instead. This is not a small risk to weigh up — ingested gel and plastic backing can cause a blockage, and towels do the same job with none of that concern.
Check the edges every day when you spot-clean. It takes seconds.
Preparing new fleece
New fleece has a manufacturing finish that stops it wicking entirely. Wash hot and dry hot two or three times before first use, then test by pouring a little water on it. It should pass straight through rather than bead on the surface.
Never use fabric softener or dryer sheets, at any point in the fleece’s life. They coat the fibres and destroy the wicking permanently.
The toilet corner exception
Keep loose absorbent bedding or a litter box in the corner the animal uses as a toilet, rather than running fleece across the whole floor.
It concentrates the mess somewhere that can be scooped daily, keeps the fleece cleaner for longer, and stretches the laundry interval considerably. Litter boxes with integrated hay racks are under litter boxes and hay feeders.
The daily and weekly routine
- Daily: scoop the toilet corner, shake loose hay off the fleece, check the edges are still tucked.
- Every two or three days: swap the fleece for a clean set and replace the absorbent layer.
- Weekly: strip everything, wash the base, dry fully, reassemble.
In a Phoenix summer, the middle step comes round faster. Heat accelerates ammonia production and nothing dries as slowly here as it does elsewhere — that part, at least, the climate helps with.
Two sets, minimum
One set of liners means the habitat has to wait for the washing machine. Two sets means the swap takes two minutes and the dirty set can wait for a convenient load.
This is the single change that makes a fleece system stick rather than being abandoned after a month. Liners and mats are under mats and cage liners.
When fleece is the wrong choice
For burrowing species — hamsters, gerbils — a flat liner denies a strong natural behaviour. Those animals need depth of loose bedding rather than a fabric floor, and no layering system substitutes for it.
Fleece suits guinea pigs and rabbits, who sit and run rather than tunnel.
Cooler options for summer
Fleece traps warmth, which is welcome in winter and less so in July. Swapping part of the floor for a woven grass mat gives a cooler surface with airflow through it, and lets the animal choose where to lie.
There is a full guide to grass mats elsewhere on this journal, and a summer care guide covering the rest.

Key points
- Fleece wicks but does not absorb, so it always needs an absorbent layer beneath it.
- Training pads work well as that layer, but only under a barrier — they are not chew-safe.
- Any animal reaching the pad through a gap must have it removed; ingested gel is dangerous.
- Layer order: waterproof base, absorbent layer, fleece top, with the fleece tucked so nothing is exposed.
- Keep the toilet corner on loose bedding rather than fleece — it is easier to spot-clean daily.
- Two full sets of liners make the system sustainable; one set means gaps in the routine.
