The microfiber bath mat wins on every practical metric for normal use: it's cheaper, it actually washes clean, and its shaggy pile actively brushes litter off paws rather than just catching what falls. The carpet runner is a niche solution — genuinely excellent when you need to cover 10+ square feet, but overkill and worse at the core job for a standard single-box setup. Reddit has independently converged on the bath mat recommendation across multiple threads, which is about as close to a consensus as you get.

You can throw a microfiber bath mat in the washing machine and actually get it clean. A carpet runner can be vacuumed, but vacuuming a litter mat is a partial solution — fine litter dust, odor, and bacteria stay embedded in the pile. Over time, a mat you can't properly wash becomes a hygiene problem, not just a mess problem. The bath mat resets to genuinely clean every time.
A pre-cut bath mat tops out around 20x32 inches. A carpet runner from Home Depot can be cut to 3x10 feet, 2x6 feet, or whatever your laundry room demands. For multi-box setups or awkward closet configurations, no bath mat can compete — you'd need three of them overlapping messily. If your situation requires custom coverage, the runner wins by default.
This is the difference that matters most for litter tracking. A carpet runner traps litter that falls off passively. A microfiber bath mat with high pile physically brushes against a cat's paws as they walk through it, dislodging litter that's stuck between toes. That's why Reddit users who switched to bath mats consistently report less tracking across the house — it's not just catching litter, it's removing it at the source.
A single bath mat is $10-$15 and covers a standard box. A carpet runner starts around $15 but you're often buying more than you need for a single-box setup. Where the runner gets cost-competitive is large coverage — a $25 runner covering 6 square feet beats buying three bath mats at $30 total. For one box, the bath mat is the obvious budget winner. For large setups, the math flips.
