A side-by-side comparison based on expert reviews and real community consensus.

Tidy Cats Tidy Feet wins on pure anti-tracking engineering — the larger clay granules are a purpose-built solution that actually works, and its 82/100 consensus score reflects that. SmartCat is the better litter in a vacuum: zero dust, no food-crop contamination risk, and tighter clumps than most plant-based alternatives. The tradeoff is availability and compatibility — Tidy Feet works in automatic boxes and is easier to find in stores, while SmartCat is a Reddit sleeper pick that requires more effort to source and won't play nice with your Litter-Robot.

Tidy Cats literally redesigned the granule shape and size to stop litter from lodging in cat paws — that's the entire product brief. SmartCat tracks less than clay because grass seed granules are naturally less clingy, not because anyone optimized for it. If tracking is your primary complaint, purpose-built beats incidentally-better every time.
SmartCat is genuinely zero dust. Tidy Feet is low dust for a clay litter, which is a much lower bar. If you've ever watched a cloud billow out of a clay litter bag, you know the difference matters — especially for cats or owners with respiratory issues. Tidy Feet's larger granules do reduce airborne particulate compared to fine clay, but they're still clay, and clay still produces dust.
Tidy Feet works in automatic litter boxes — there's even a Reddit report from a Litter-Robot 4 user praising it specifically. SmartCat's lightweight formula is explicitly not recommended for automatic boxes. If you've spent $500+ on a self-cleaning litter box, this isn't a minor footnote — it's a dealbreaker.
This one matters if you've been using corn-based litters. SmartCat's grass seed base means no aflatoxin-producing fungus risk that plagues corn litters. Tidy Feet is clay, so it sidesteps the issue entirely from a different angle. But if you're switching away from corn specifically because of contamination concerns, SmartCat is the plant-based upgrade that doesn't carry the same baggage — and the Reddit community has flagged this explicitly.
