Overview

["The ikuso cat door is built from ABS plastic with a plastic frame and installs into an interior door, sized large with a pass through opening of about 8.46 by 7.87 inches. At $20.99 it's priced as a straightforward hardware accessory rather than a premium pet gadget, and it's meant for the common job of hiding a litter box behind a closed closet or bathroom door.", "It's rated for pets up to 33 pounds, which covers the vast majority of cats and many small dog breeds, so it works in multi pet homes where a dog might also need to slip through. The compatible door thickness runs from 1.78 to 2.45 inches, which fits most standard interior doors but is worth measuring before ordering.", 'With 847 reviews and a 4.6 star average, plus about 50 units bought in the past month, this door has a solid track record among buyers looking for a simple, no frills solution to the closed door litter box problem.']
