If your cat stopped using the litter box after a hood or enclosed box was added, do not change the litter, location, cleaner, and box style all at once. Give the cat an open option with the same familiar litter in a nearby acceptable location and compare use. A cover can change odor concentration, entry space, visibility, and escape routes even when the floor footprint looks large enough to you.
Side-by-side test
Change the box shape while keeping the other variables boring
Use a roomy uncovered box with an entry the cat can step into comfortably.
Keep the current box available if it is clean and safe, but do not force the cat inside.
Use the cat's familiar unscented litter in both options so the trial is about the box, not a new substrate.
Scoop both regularly and avoid strong cleaners or fragrances that make one option smell dramatically different.
Look at the usable interior, not the outside dimensions
- The cat should be able to enter without squeezing through a narrow doorway or brushing the back on a low hood.
- There should be room to turn, dig, and choose a position without the tail or hips being forced against the wall.
- A senior cat or a cat with mobility changes may need a lower entry even if a tall-sided box used to be manageable.
- In multi-cat homes, an enclosed box can make it harder to see another cat approaching or to leave in more than one direction.
What the location of the accident can tell you
The cat reached the area but may dislike the entry, enclosure, litter, cleanliness, or physical effort required to get inside.
The cat may be developing a surface preference or avoiding the current litter-box setup for another reason.
Urine marking is a different pattern from squatting to empty the bladder and deserves a separate behavior and medical assessment.
Keep the successful option before removing the rejected one
Once the cat reliably uses one setup, leave it stable long enough to learn what mattered. If the open box wins, you do not need to turn the home into a series of product experiments. The useful answer may simply be that your cat prefers an uncovered, easier-to-enter box.
Contact a veterinarian when litter-box avoidance is new or comes with frequent trips, straining, crying, blood, excessive licking of the genital area, vomiting, lethargy, or changes in thirst. A cat that repeatedly strains and produces little or no urine needs urgent veterinary care, especially because urinary obstruction can become life-threatening.
Product comparison note
What to compare if equipment may help
Compare litter-box products by usable interior dimensions, entry height, ease of turning, cleaning access, visibility, and whether the cat can enter and leave comfortably without a restrictive hood or narrow doorway.
