A practical step-by-step routine for lining a cat litter tray with drawstring hygienic bags, including how to choose between FPI 5362 and FPI 5363.
Quick answer
Fit a drawstring hygienic bag over the tray rim before adding litter, press it flat against the base, then lift the bag out by its strings when you scoop. Choose the bag that matches your tray: FPI 5362 for Nip 20, Nip 20 Plus, Bella, Prima and Moderna trays, or FPI 5363 for Maxi Bella trays.
Why the bag has to match the tray
A liner only helps if it stays put. A bag that is too small will pull off the rim when your cat digs, while an oversized bag bunches in the corners and lets litter slip underneath. Ferplast lists FPI 5362 as suitable for Nip 20, Nip 20 Plus, Bella, Prima and Moderna litter trays, and FPI 5363 as suitable for Maxi Bella trays. Check your tray model before buying, and if the tray is not on either list, treat the fit as unconfirmed rather than assuming a standard size will work.
When a liner is the wrong choice
Some cats scratch through thin plastic or chew at loose edges, and a torn bag defeats the purpose. If your cat is a persistent digger, a liner may create more mess than it saves. Liners also add a layer between litter and tray, so clumps can stick to the plastic instead of the tray surface. In that case, scoop daily and wash the tray weekly instead of relying on a bag.
Step-by-step: lining and changing the bag
- Empty and rinse the tray: Tip out all old litter into a waste bag, then rinse the empty tray with warm water and a pet-safe cleaner. Dry it fully before lining. Common mistake: lining a damp tray, which makes the plastic cling and tear as you smooth it. A dry tray is easier to line and less likely to rip the bag.
- Check the bag against your tray model: Match the bag to the tray before opening it: FPI 5362 for Nip 20, Nip 20 Plus, Bella, Prima and Moderna, FPI 5363 for Maxi Bella. Checkpoint: if your tray is not listed, do not force the bag — an unconfirmed fit is likely to slip.
- Open the bag and settle it over the rim: Open the bag fully, place it inside the tray and fold the top edge over the rim all the way around. Smooth the base with your hand so the plastic sits flat in the corners. Common mistake: leaving air pockets under the bag, which collapse when your cat steps in. Run your hand around the inside edge to confirm the bag is caught on the rim.
- Add litter to your usual depth: Pour in the same amount of litter you normally use, roughly 3–5 cm for most cats, and spread it evenly over the bag. Checkpoint: keep the bag edge visible above the litter line so you can grab it later.
- Scoop daily and check for tears: Scoop solids and clumps daily as part of your litter tray cleaning routine. While scooping, look for holes or litter that has slipped under the bag. Common mistake: ignoring a small tear, which lets urine reach the tray and defeats the liner. Replace the bag at the first sign of a tear rather than waiting for the weekly change.
- Lift out by the drawstrings and dispose: Pull the drawstrings to close the bag, lift it clear of the tray and dispose of it with household waste. Then wipe the tray and fit a fresh bag. Checkpoint: never flush the bag or its contents.
