Omlet Cat Litter No. 1 - Silica - 8.75L

by Omlet

Ultra Hygienic & Absorbent

Silica Cat Litter is made from small sand particles that are highly absorbent to reduce moisture and odour in your litter tray, keeping it fresh and hygienic for much longer. Not only do these small grains absorb and dry faster than other litters, their fine nature means the litter does not stick to paws and get tracked around your home.

Thanks to its clumping nature you can spot clean the tray without having to replace all of the litter, minimising waste and reducing the amount you use. The clumps can easily be picked up and thrown away, so cleaning up after your cat can be simpler and more pleasant than ever!

No.1 Silica Cat Litter is an improved version of the Igloo Snow formula that used to be available on the Omlet website. It is very very similar, but now has the added feature of being clumping, which improves longevity and reduces waste.
Indoor cats and frequent litter tray users would benefit from a clumping cat litter, as these make it easy to remove the used litter without waste, improving longevity of the litter. Try Omlet’s clumping cat litters: No. 1 Silica, No. 2 Tofu or No. 4 Clay.
Multi-cat households need a long lasting, clumping litter with excellent odour control and absorbency. Try Omlet No.1 Silica Cat Litter.
Non-clumping cat litters are recommended for kittens to prevent stomach upset from ingesting the litter. A softer litter is also better for their sensitive paws. Try Omlet No.5 Paper Cat Litter.
Clumping litters, such as No.1 Silica Cat Litter, can help with odour control as they are extremely effective at absorbing moisture and odours, and make it easier to remove all the used litter from the tray without leaving any smell behind. Some litters are also available with active carbon particles to neutralise odours in the same way litter box carbon filters do, such as No.2 Tofu and No. 4 Clay. Other litters may have a natural fresh scent to them which helps to mask the bad odours, such as No.3 Pine.
Cats with allergies and sensitivities will appreciate a softer cat litter which produces minimal dust in the litter tray. Our most hypoallergenic formulas are No.5 Paper and No.1 Silica.
Clumping cat litters absorb moisture to form a clumped piece which is easier to remove from the litter box, while reducing waste. Some clumping litters are softer and good for kittens and cats with sensitivities, such as No.1 Silica, while others offer supreme absorbency power while neutralising bad odours with active carbon particles, such as No.2 Tofu and No. 4 Clay.
Some litter granules can get stuck to your cats feet or fur and be dragged out of the litter tray with them. You may then spot these granules around your home as they fall off your cat - this is called litter tracking. Non-clumping litters can be effective at reduced tracking as they are often made of larger pellets which don’t get stuck to your cat as easily, such as No.3 Pine and No. 5 Paper. Very fine, soft gains can also reduce tracking as they slip straight off your cat’s feet and fur, such as No.1 Silica.

Latest Product Reviews For Omlet Cat Litter No. 1 - Silica - 8.75L


The only cat litter my Persian will use! - Jules, Cambs,

Tried all the cat litters available and found this the only one my fussy Persian will use. No tracking and soft in his feet. Well worth the money and can’t recommend it highly enough! 2

Omlette cat litter - Kaylee, Cambs,

It’s really good because no smell at all and last longer 2

not great- fast delivery - Denise, Cambs,

I just switched to silica n1 from the clay as I wanted something less dusty. It's not what I have expected it to be. I have a 4 month siberian, so the usage is very little. However, the urine sets at the bottom and gets stuck to the litter box making it difficult to clean and for the clumped sand not to crumb in a million pieces, the smell is so strong that the cat smells of urine too when it uses it. It's been 2 days and I already need to change it completely and clean the box. I will definitely go back to the Clay option that was easy, clean and lasted over a month. 2

Awful! - Shirley, Cambs,

I don't normally write reviews unless super positive...but this is beyond awful! I purchased two bags as I knew I would need to use 1.5 bags in the giant litter tray my kits have...absolute waste of £30! Did not clump sufficiently and the odour of urine was terrible! Not only that, its all over my floor which I crunched to powder when I walked on it...and its a hooded tray! I swapped to this as I hadn't realised clay litters were so bad for the environment...the reviews seemed positive and I didn't mind paying extra given its supposed to last longer....well, not in this case...so bad I swapped back to my old litter after only one day. Had cats for over 20 years and this is the worst litter ever! Sorry Omlet, but it had to be said! On a positive note, I've had the Qute cage for 5yrs and its amazing! 2
