Silica gel, or Synthetic Amorphous Silica (SAS), is a form of silica that has been widely used in topical and oral medicines, foods, and cosmetics for decades. They are inert, clear crystals made from naturally occurring minerals that have super absorbent properties.
Because silica gel litter is known for its excellent moisture absorption and odor control capabilities, it has become a popular and modern choice for cat parents everywhere.
Silica Gel Myths & Safety: What Cat Parents Should Know
Silica gel pops up in all kinds of everyday products, and it's completely normal to have questions -- especially when it comes to your pets. Here's a quick, science-backed breakdown on two of silica's biggest misconceptions to help you feel confident about silica gel in crystal cat litter.

Myth: "Do Not Eat" Means Silica Gel Is Toxic
Here's the reality: the warning is about choking, not poison. Those tiny packets in shoes and snacks say "do not eat" because they're small, hard, and not meant to be swallowed -- not because silica gel is chemically harmful. Silica gel itself is non-toxic, but packets should always be kept away from curious paws and mouths to prevent choking or stomach upset.

Myth: ALL silica is the SAME
Here's the reality: crystal-based cat litters use the safe kind. Amorphous silica gel is the type used in high-quality crystal litters (including ours!). It is non-toxic, super absorbent, and low dust. Crystalline silica is the harmful form tied to long-term, high-level occupational exposure. It is NOT used in any silica-gel based cat litter.
The Bottom Line
Silica gel's safety warnings stem from choking risks, not toxicity. And crystal litters are made with the safe, pet-friendly form of silica gel.
