Quick answer

Fit the PuraMax Fence by seating it at the raised entrance of your PuraMax and pressing until it sits flush. This simple height addition reduces litter splashing and helps keep urine inside the box. Check that the fence does not block the cat's path or the waste drawer before you rely on it.

What the PuraMax Fence actually does

The PuraMax Fence is an elevated entrance piece made of high-quality PP material. It is non-toxic, odorless, and easy to clean. By adding height at the entry, it reduces litter splashing out of the box and minimizes the chance your cat urinates outside the litter box. It is not a lid or a full enclosure, so it will not stop a determined digger from kicking litter over the top. It works best as one part of a broader scatter-control routine.

Before you start: check the fit and clearance

Confirm your litter box is a PuraMax model, because this fence is designed for that entrance shape. Clear the area around the box so you can kneel and see the entry from your cat's height. If you already use a litter mat, slide it back temporarily. A common mistake is forcing the fence when the box is not level or when litter has built up under the entrance lip. Wipe the entry edge with a damp cloth and let it dry so the fence seats without grit in between.

Step-by-step: how to fit the PuraMax Fence

Work on a flat floor with the box unplugged if you need to move it. Keep the fence oriented so the raised lip faces outward, away from the interior. Press evenly along the base rather than one corner at a time. After fitting, watch your cat use the box once before you walk away. If your cat hesitates, remove the fence for a day and reintroduce it after a successful use.

Common fit problems and how to solve them

If the fence feels loose, check for litter granules trapped in the groove and reseat it. If your cat avoids the box, the added height may be too abrupt; give it a day and keep the area quiet. If urine still escapes, the issue may be the litter level or the box position, not the fence. In that case, lower the litter fill slightly and make sure the box sits on a hard, level surface. The fence is a low-cost add-on, but it cannot fix a box that is too small or placed in a high-traffic corner.

PuraMax Fence fitting steps

  1. 1. Confirm the model and clear the entry: Check that your box is a PuraMax, then remove the old litter mat and wipe the entrance edge clean and dry. Grit or moisture stops the fence from seating flush. If the edge is damaged or warped, do not force the fence.
  2. 2. Orient the fence correctly: The raised lip should face outward, away from the inside of the box. If you fit it backward, it will not add height where your cat exits. A quick visual check now saves a redo later.
  3. 3. Press evenly along the base: Set the fence in place and press down along the full base with both hands. Work from the center outward so it clicks or seats evenly. A loose corner means it is not fully seated.
  4. 4. Test with your cat: Let your cat approach the box normally. Watch for hesitation or jumping over the fence. Most cats adjust within a day. If your cat avoids the box, remove the fence for 24 hours and try again.
  5. 5. Check daily for the first week: Look for litter trapped under the fence and wipe it clean. Also confirm the fence has not shifted after the box cycles. A weekly wipe keeps the fence easy to remove and refit.

Product facts
