How to Remove Cat Urine from a Memory Foam Mattress
Cat urine on a memory foam mattress can leave a stubborn stain and odor, but you can tackle it with an enzymatic cleaner and gentle blotting. Here's a practical guide for fresh and dried accidents, with memory foam-specific precautions.
Cat urine on a memory foam mattress is one of the toughest pet stains to handle. The foam is highly absorbent, so the urine can soak deep below the surface, leaving both a visible stain and a lingering odor. But with the right approach and a good enzymatic cleaner, you can remove both fresh and dried accidents without damaging the mattress.
What to Do First
Act quickly if the accident is fresh. The sooner you start, the easier it is to prevent the urine from soaking deeper into the foam. If the urine has already dried, don't worry—the method below still works, but it may take a little more patience.
