Consider Your Cat's Preferences
Most cats prefer fine-grained, sand-like textures. If switching from clay, look for natural alternatives with similar granule size. Some cats dislike the feel of pellets initially.
Think About Odor Control
If odor is your main concern, activated charcoal/biochar options offer the most powerful natural odor elimination. Wood and wheat also have good natural odor-fighting properties.
Environmental Impact
If sustainability matters to you, look for plant-based options like corn, wheat, or wood. These are renewable and often compostable. Clay is natural but not renewable.
Your Cat's Health
For cats with respiratory sensitivities, paper and wood pellets tend to produce the least dust. For post-surgery cats, paper is often recommended as it won't stick to wounds.
