Not Same Microguard

I have used this litter since it came out, it controlled the smell but not anymore The litter is a now different color and consistency with the mild scent gone, The price has gone up quite a bit plus making only 28lb boxes now, no more 14 and 19 lb boxes. Over the years I really felt it controlled the bacteria growth and odor but not anymore. Unable to complain to Arm & Hammer. They make it impossible to get in touch with them.

Low Dust, Soft on Paws

When our three cats gravitated to this litter despite having other boxes to choose from, I thought we'd found litter box bliss. There was virtually no dust when I poured the litter in to their box. The small grains of clay look and feel like sand - soft on paws and minimal tracking. Even though the clumps formed are not hard, the waste is still easy to remove and doesn't leave a lot of debris that slips through the scoop. Where this litter comes up short is on odor control. It does contain the smell of waste and urine, but the scent that remains is one of wet cardboard. I'm using the Arm & Hammer Litter Deodorizer with this litter and cleaning daily, but nothing gets rid of that smell!

Cat allergic to new microgard

My cat has loved all the Arm and Hammer products, this new version he seems allergic too. I ordered 2 boxes, and he has been itching for 2mo. I had to put him on antibiotics for 12 days and went back to the original Arm and Hammer clump and seal multi, and he is so much better. Very unfortunate outcome for him.

Smells WAY too strong.

Not a great litter if you are sensitive to strong fragrances. The smell is nauseating. 100% would rather light a candle to neutralize the smell of cat poop than use this litter. It’s unfortunate that they don’t have an unscented alternative for this specific line of litter because it otherwise seems heavy, low tracking, and small grains so soft on paws.

Neat litter

This is the litter to get if you cat tracks it every where or digs it out of the box covering up it’s deposit. So far it is working. Is very good about clumping and it does slide right off the side or bottom of the box when removing.

Clumps well

Tried this litter because I had delivery issues with Scoop Away. This is a good alternative, but more expensive. J

Threw It Out

This litter has no dust but has its own scent that nearly made me sick. I ended up throwing it away.

Excellent litter

This is one of my go to litters for a multi-cat household. Holds up smells really good, clumps perfectly and has minimum dust. Well packaged and easy to pour. Doesn’t stick to cats paws too much and they have bo problem with walking on it.
