A litter tray liner only earns its keep if it survives a cat digging before the scoop goes anywhere near it, which is the one thing a thin liner never manages.

These are extra-thick liners made from 90% post-consumer recycled polyethylene, with a small amount of virgin plastic and colouring making up the rest. You open the liner inside the tray, fold the excess over the rim, then fill with litter as normal; when it's time to change, the drawstrings pull the liner shut for a straightforward, contained disposal in household waste. They come in a pack of 24 and in three sizes — small, medium and large — sized to different trays; the largest is built for trays up to 49 x 43 x 38cm.

• 90% post-consumer recycled PE, plus a small amount of virgin plastic and colouring
• Drawstring closure for a tied, contained disposal
• Fold excess liner over the tray rim before adding litter
• Pack of 24
• Sized for trays up to 49 x 43 x 38cm (largest size)
• Not suitable for flushing or composting

One limit worth flagging. Beco are explicit these are for the household bin, not the toilet or a compost heap — a recycled-plastic liner doesn't break down the way loose litter might. The size only fits the tray it's rated for, so measure your tray rather than assuming a size based on your cat.

Who it's for: owners who want the tray protected from scratching and staining, with disposal reduced to pulling a drawstring rather than scraping the tray out by hand.
