Silica Gel Cat Litter
Means No More odor

Synthetically produced from sodium silicate, Silica Gel cat litter is a porous, granular and vitreous form of silicon dioxide.

This type of cat litter resembles small, irregularly shaped pieces of glass and exhibits properties dissimilar from traditional clay cat litter, such as its hardness and powerful drying ability.

Silica gel is that material used in small packets that are placed in various perishable and non-perishable goods to control humidity and prevent spoilage.

Before it was developed as a cat litter, silica gel was used during World War II as a way to keep penicillin and military equipment as dry as possible, especially when these items were exposed to the hot, humid environments of southern Japan.

Larger silica gel packets are also kept in libraries and museums housing valuable paper artifacts to regulate humidity levels and inhibit damage to these documents caused by condensation and moisture in the air.

Advantages of Silica Gel Cat Litter

  • Non-flammable and non-toxic (cats that accidentally ingest silica gel may suffer slight gastrointestinal issues or none at all)
  • Highly absorbent
  • Provides better odor control than clay litter
  • Because of its powerful absorbency, silica gel does not stick to the sides of the litter box, allowing for easier clean-up
  • Dust free
  • Resistant to bacterial and mold growth
  • Can be flushed down the toilet
  • Biodegradable

Disadvantages of
Silica Gel Litter

  • More expensive than clay cat litter--ten pound bags may cost between $10 and $15
  • Due to the shape of the crystals, they can sometimes get caught between a cat's toes, allowing the cat to leave pieces of the litter all over the house
  • The texture of the litter may repel some cats that do not like the sharpness corners of the crystals
  • Scented silica gel litter may also repel cats that are sensitive to strong odors.
  • When the gel becomes over-saturated, urine will start to pool at the bottom of the litter box. Owners may not realize this because silica is so efficient at absorbing moisture.

Health Meter Early
Detection System Cat Litter

A French import created by a veterinarian, this unique cat litter can detect certain health problems common to cats when the cat urinates on the crystals.

If the litter changes color, this indicates the possibility that a bladder infection or kidney/liver disease may exist and should be checked out by a professional.

Color-coded crystals contain chemicals that react to urine that has extreme pH levels.

For example, if a cat has a kidney infection, the crystals will turn green. Cats that have kidney stones and urinate on Early Detection silica gel cat litter will cause the litter to turn red.

Owners should be aware that the color change needs to be a dramatic one rather than a slight one to warrant taking a cat to the vet for a check-up.

Clay/Silica Gel
Combination Cat Litter

Some owners prefer using a combination clay/silica gel simply because their cat prefers it over all silica gel litter. Cats that have always used clay litter may refuse to even enter a litter box full of all-silica gel litter.

Introducing a cat to silica gel by using a mixture of the two materials may be one way of acclimating a cat to something totally different from what he has become accustomed.

Types of clay/silica gel combo-litters are:

  • Tidy Cats Scoop Power Blend
  • Ever Clean Multi-Crystal Blend
  • Fresh Step Plus Dual Action Crystals Cat Litter
  • Scoop Away Cat Litter Plus Crystals
