Very dusty

I gave this litter a try for my cat with asthma as she has begun having issues with clay litters. I was impressed with the clumping performance and odor control. My cats transitioned to using it no problem. BUT this litter is VERY dusty and while it did not make her cough the dust and pieces stuck on her fur has likely caused her to be nauseous after grooming herself (per the vet who ruled out a hairball or other causes). I’ve had to stop using the litter after two weeks because of this.

once they adjusted to the texture it was fine

I love this litter because it is lightweight and really there is minimal odor. I do clean boxes multiple times per day. Cats did need to gradually adjust to it (I followed instructions on package). It is cost-effective. They do track it but they do that with most everything. I tried the scented version and they all hated it. I will stick with this one. It does actually clump and takes a bit of adjustment with your scooping but well worth it.

Makes house smell like a barn.

At first I couldn't understand why my house smelled like a barn. The litter box was in the basement but it was the scent when entering my home and in the kitchen with the door close to the basement.

Multiple Uses!

I've only just recently switched to Catalyst and because my fur kids are so picky, I was cautiously skeptical. But they did not seem to be "offended" by the gradual switch from clay to wood. It absorbs odors beautifully and doesn't track all over the house like clay pebbles. In the first few days after I started using, one of my "kids" had an accident on the living room hardwood floor (had to take him to the ER, long story, but he's fine now!). On my way out the door, I remembered how janitors in elementary school would use sawdust to clean up "accidents" so I tossed a couple of handfuls onto the mess so I could clean it later. STUNNING RESULTS! The wood absorbed not only the excess liquid, but also the SMELL. What I was anticipating to be a gruesome clean-up was EASY PEASY!

Stormy likes this!

I started by mixing this into Stormy’s clay litter for the first week or so. He started using the box with the Catalyst in it exclusively. The smell is nice, not overly strong, and the tracking is minimal.

My cats hate it. I put it in one of my 3 cat boxes and the cats avoided it and went back to the clay boxes. I tried mixing it with the clay litter -- it didn't help. It smells nice, but there are little pieces of wood all over the house. It's difficult to sweep up, so I have to vacuum it up. Going back to clay litter.

I wanted to love it, but it’s just bad!

This litter is not there yet. I’ve never had such an insane amount of dust from a litter ever before, it covered everything in a thick coat of dust. It forms ok clumps but not the best. The only redeeming qualities are that it is lightweight and it has decent odor control for a natural litter. It tracks everywhere and sticks to kitty, clothes, carpet, everything! My cat started having upper respiratory issues (which she never had before) after only 3 days using only catalyst… and I did too! We had to throw it out, the entire bag, what a waste! I hope they can improve because I want to love it, I love the message but I just don’t believe it is safe for ANY cats or people at this current point in time.

Catalyst litter

I will add a little to her current litter and hopefully she’ll take to it. She’s not good with change.

It works for us

It definitely helps with the smell and clumps well * as long as you keep on top of it like most clumping litters* if you don’t scoop at least every other day eventually the clumps will not hold. My cat is good with it and I like that it’s natural.

not good for older cats

This litter not great for older cats or cats that pee large amounts. The litter get in between their toes and fur and turns super hard. Not ideal at all.
