Dr. Elsey's Ultra Premium Clumping Cat Litter vs Purina Tidy Cats 24/7 Performance Clumping Litter

Buy Dr. Elsey's Ultra if you want an unscented, low-dust clay litter for a multi-cat home or a cat with sensitivities; its fine, heavy granules clump hard and track little. Buy Tidy Cats 24/7 Performance if you prefer a scented litter with a slow-release deodorizing system and a resealable pail. Both are scoopable clay litters that hold up in multi-cat boxes; Dr. Elsey's leans on clumping strength and dust control, Tidy Cats on scent and packaging. Owners of both report solid odor control, though scented litter can bother sensitive cats and people.

• Choose the Dr. Elsey's Ultra if you want an unscented, near-dust-free clumping litter that forms firm clumps and suits cats with allergies or aversion to perfume.
• Choose the Tidy Cats 24/7 Performance if you want a scented litter with continuous odor control and a sturdy pail that keeps litter dry and contained.
