There are many different types of litter alternatives that you can use for your cat, but one of the most effective (and inexpensive) options is sawdust or wood shavings. Both of these materials do a great job of absorbing urine, so your cat's litter box will stay clean and smell fresh. Plus, your cat will love scratching and digging in the soft wood shavings! Another benefit of using wood shavings instead of cat litter is that it has a strong natural scent to mask the unpleasant odors of cat’s urine and feces. And because of its texture, it won’t stick on kitty’s claws, so there are no tracking issues.
