Real reviews from real pets (with help from their parents)
I bought four brands of stain remover. This by far is the best brand! It smells great and works like a dream. I reordered 5 bottles!!
Ronda S.
I sprayed it on a spot that my dog definitely claimed as his own, and a few minutes later… nothing. No cover-up scent, no weird chemical smell — just gone.
Sarah M.
It didn't mask the pee smell, it eliminated it. Seriously! This was like smelling clothes that just got taken out of the dryer. Just nice and clean.
Nicole R.
I sprayed this on a spot, let it soak overnight and guess what? The smell was completely gone. The bottle is a nice large size, so it's a good value for your money.
James T.
Not only did it take care of the spot, but she hasn't used it since! Coincidence? Maybe. But she was regularly using that spot and in 4 days since hasn't used it again.

I've tried a lot of different products, and very few work well. I'm really impressed — it worked well to get out such a tough stain and made the treated spot smell fresh and clean.

What Pet Parents Are Saying
Finally something that WORKS
I've tried Nature's Miracle, Angry Orange, vinegar, baking soda — nothing worked on my cat's favorite spot behind the couch. Ona actually eliminated it. Completely. I'm shocked.
Safe for my cats — that was the deal-breaker
Most enzyme cleaners have d-limonene which is toxic to cats. Ona doesn't. That alone made it worth trying. The fact that it works better than everything else is a bonus.
30 years of science isn't marketing fluff
We foster dogs and go through a LOT of cleaner. Switched to Ona 3 months ago and haven't looked back. It handles the worst accidents — even old set-in stains in the basement carpet.
No more embarrassing pet smell
I was the friend whose house 'smelled like dog.' Couldn't even smell it myself anymore. Two treatments with Ona and my sister said she couldn't detect anything. Life-changing.
Works on hardwood without damage
My golden retriever had a spot by the back door on our hardwood. Other cleaners stripped the finish. Ona cleaned it without any damage to the wood. Professional-grade stuff.
The enzyme cleaner vets recommend
Our vet actually recommended an enzyme cleaner for our senior cat's accidents. Tried Ona based on the ingredients list — no harsh chemicals, no citrus oils. Works perfectly.
