The Scoopfree litter box is a self-cleaning box. It is ingenious invention for busy pet parents. It uses a raking system to move the waste into a covered compartment and disposable crystal litter trays to keep the litter box clean with little effort. Simply set it up and forget about it – your cat will love it! So next time you’re looking for an easier way to keep your litter box clean, the Scoopfree is definitely worth checking out! Unfortunately you can’t use regular litter in scoopfree litter boxes. Instead, it is best to use its own unique crystal litter trays to make it work as expected. However, Crystal litter does have its pros and cons just like any other pet product. The crystal litter tray is a great way to keep your pet’s litter box clean. It has a special raking system that pulls solids and soiled crystals into the waste trap. So when it's cleaning time, just throw the entire tray into the garbage. No more scooping and scrubbing! In fact, there are some other significant benefits to using crystal litter. For one, it is much more absorbent than clumping litter and has superior odor control, so it’s great for homes with multiple cats. Additionally, crystal litter is virtually dust-free, so it’s a good option for cats with allergies and respiratory risks. If you have one cat, you should expect to change your litter tray every month or so. This timing will obviously vary depending on how often your cat uses the litter box, but it’s a good general guideline. If you have multiple cats, you may need to change the tray more often, since there will be more waste. Factors like these should be taken into account when deciding how often to change your litter.
