The Best Crystal Cat Litter

PetSafe’s Scroop Free crystal cat litter is a feline favorite that reputably has five times better odor control than clay clumping litter. Each pre-portioned litter bag is measured to last up to thirty days for one cat, who’ll feel as relaxed as can be thanks to this crystal litter’s lavender aromas. Plus, you won’t find this low-tracking crystal litter anywhere else around your home other than your cat’s litter box!

Prospective customers may be concerned over the lavender scent. However, it’s important to note that this scent is free of perfumes and dyes, thereby making it compatible with sensitive cats. Your feline fusspot will probably be too relaxed from the lavender scent to care, anyway.

Best Crystal Cat Litter Buying Guide & FAQ

Features To Consider Before Buying Crystal Cat Litter

Does the litter that I’m looking at contain a fragrance or scent?: Although silica litters typically don’t have any fragrances or scents, a few of them go against the grain. In fact, our top pick of this buying guide – PetSafe’s ScoopFree Premium Crystal Non Clumping Cat Litter – boasts a light lavender scent to help reduce cats’ stress. And although cat owners will love these relaxing aromas, pernickety cats most likely won’t take to it kindly.

Does it clump?: The majority of crystal cat litters are non-clumping. However, if you want the best of both worlds, silica gel cat litter that does clump exists – take Ultra Pet’s Clumping Crystal Cat Litter as an example!

Benefits of Using a Silica Gel Cat Litter

This type of litter does not generate the harmful dust clay litter is known for: For owners who suffer from dust allergies, the fact that silica litters don’t generate much dust is a lifesaver. Say goodbye to the airborne clouds that arise every time your cat goes through their litter tray!

Your cat’s paws will appreciate their new litter: Boasting a soft, silky exterior, cats will love the feeling of walking over their litter tray. Senior cats in particular will be grateful and will certainly notice the difference between the soft silica and the hard clay litter that would poke into their sensitive paws.

How Do Silica Cat Litters Work?

Nobody is able to see the tiny pores that silica gel granules contain. But know that they do exist. These pores effectively absorb the moisture and urine that cats come into contact with. If you can still smell a stench coming from your litter box, stir up your cat’s litter tray to allow these pores to successfully come into contact with the urine and moisture to facilitate optimal absorption. With the help of silica cat litters, you’ll never find a disgusting pool of cat urine at the bottom of your litter tray again.

Crystal Cat Litter Concerns

Silicosis: Although the chances of your cat developing silicosis are incredibly rare, it does indeed happen. If your feline friend inhales a lot of microscopic silica dust particles, they could develop silicosis – a form of occupational lung disease.

Cobalt Chloride: This inorganic compound is a sky blue crystalline solid that is used to due most crystal litter blue. Classified as a class 2B carcinogen by IARC, cobalt chloride may trigger skin allergies in cats and can be lethal if ingested.

Best Crystal Cat Litter FAQ:

Q: How often do I change crystal cat litter?

A: As moisture evaporates around the silica litter, it is absorbed via the pores. This means that you won’t have to touch your cat’s litter tray for approximately two weeks a a time. If you have a multi-cat household, you may ned to change their litter tray more regularly.

Q: Why are most silica cat litters non-clumping?

A: As the tiny silica gels absorb moisture and odor to such an extent through their small pores, they are incapable of clumping. Silica litter consists of quartz sand and its unique atomic structure doesn’t allow for clumping.

Q: Are all crystal litters biodegradable?

A: Unfortunately, not all crystal litters are biodegradable. Exactly like clay litters, crystal cat litters are sourced through strip mining. This process involves mining companies bulldozing everything at surface level, followed by removing the top soil down to the desired mineral. Wildlife displacement due to habitat loss and water table contamination are only a few of the destructive consequences of strip mining.

Q: Will silica litters work in mechanical litter boxes?

A: The good news is that silica litters do indeed work in many mechanical litter boxes. One notable example is PetSafe’s ScoopFree Self-Cleaning range. Although you’re certainly looking at a little extra cost, the joy of not having to scoop up cat litter is worth it.
