The litter aisle can be overwhelming. Bags promise odor control, low dust and easy cleanup, and they are made from everything from clay to corn. Your cat’s preference matters most, since a litter your cat dislikes is a litter your cat may avoid. Here is an overview of the main types to help you narrow the choices.
Clay litters
- Clumping clay. Usually made from bentonite clay, it forms firm clumps when wet, which makes daily scooping easy. Many cats like its fine, sandy texture. It can be heavy and dusty, and it is not biodegradable.
- Non-clumping clay. Absorbs liquid but does not form clumps, so the whole box needs to be changed more often. It is often inexpensive.
Silica or crystal litters
These are made of silica gel beads or crystals that absorb moisture and help control odor. They are lightweight and can last a while between changes. Some cats dislike the feel of the crystals under their paws, and some products are noisier or sharper than others. Urine is absorbed rather than clumped, so it may be harder to monitor changes in urination.
Plant-based and recycled litters
- Pine and wood. Often sold as pellets or shavings. They can have a natural scent and tend to be lightweight. Pellets break down into sawdust when wet, which some owners like and some cats do not.
- Paper. Recycled paper pellets are soft and low in dust, and often recommended after surgery or for cats with sensitive paws. Ask your vet if they have a preference for post-operative care.
- Corn, wheat, grass and walnut. Many of these clump and are biodegradable. Texture and odor control vary by brand.
- Tofu-based. Made from soybean byproducts, these are often lightweight and clump well.
Check packaging before flushing any litter. Many municipalities and environmental agencies advise against flushing cat waste, and septic systems may not handle it well.
What about scent? Many veterinarians and cat behavior experts suggest unscented litter. A cat’s sense of smell is far more sensitive than ours, and strong fragrances can be off-putting. Good odor control usually comes from daily scooping, not perfume.
How to switch litters
Cats often dislike sudden changes. To switch, mix a small amount of the new litter into the old and gradually increase the proportion over a week or two. Alternatively, set up a second box with the new litter next to the old one and see which your cat chooses. Watch for any signs of avoidance, such as perching on the edge or going nearby.
Health notes
If anyone in the home has respiratory sensitivities, low-dust options may help. Kittens sometimes taste litter, so ask your veterinarian which type suits a young kitten. If your cat starts avoiding the box after a litter change, switch back and talk to your vet if the problem continues, since avoidance can also have medical causes.
