A bag underneath the litter and a bag inside an automatic unit's waste drawer do different jobs. Before buying liners, identify which part of the tray you mean. The cat's digging surface should follow both the unit's instructions and appropriate toileting guidance.
Consider the surface the cat touches
Cats Protection advises against newspaper and plastic liners beneath the litter because cats can find them off-putting. A liner may also become exposed during digging. Do not assume it improves the setup simply because it makes lifting litter easier for a person.
Keep waste-drawer instructions separate
An automatic tray may specify a bag or liner for its waste compartment. That is not the same as lining the area where the cat stands. Use the correct consumable and installation method for the exact unit, without allowing loose material to interfere with moving parts.
Do not improvise around damage
A liner is not a repair for a cracked or damaged tray. Inspect the underlying surface and seek appropriate replacement or care advice. Avoid covering a problem that needs attention.
Check before ordering consumables
For The Bothy, confirm the waste-drawer requirements from the supplied instructions or ask Giant Paws. Published drawer capacity does not establish that any bag of a similar volume will fit correctly.
Review the daily care requirements of The Bothy before choosing replacement consumables. Keep the cat's litter area and the collected-waste area distinct in your checklist.
