This is hands down the BEST PRODUCT for removing cat urine I’ve EVER used. I’ve tried just about ALL of the top rated products out there for cat urine where none of them worked nearly as well as or close to as My Pet Peed. I’d give it 10 out of 5 stars if I could.You can SEE it working. On cement, it started foaming and going white where the urine had been (after ripping up carpets & carpet padding, and scrubbing with only cold water (hot water sets the smell) and using a wet vac to suck it up.) No recent other products had been used for 2 years as I was dirt poor waiting on disability and had sort of gotten used to the smell. Who knows, maybe there was some residual product from years past that made it foam white…but many products won’t work on areas where other products were used. But THIS ONE WORKED!I had also used on some carpet where one of my cats had an accident (bladder crystal pain makes cats “make” outside of the litter box when they’re passing a crystal because they associate the pain with making in h th e litter box). After spritzing it with My Pet Peed, I walked away to go get a paper towel and my ADHD brain sent me on side quests for hours. When I finally returned with a paper towel, the carpet was dry and pee stain was GONE. The pee smell was GONE. And better yet, there was no weird “after smell” of the product either like many of the other options out there that people have sworn was their go-to product.I used My Pet Peed on a hairball expelled stain on the carpet. Same great result!The most amazing part is that IT REALLY DOES WORK. My mother had come over to visit and stopped dead in her tracks after coming inside my house at the front door because for the last few years apparently my house smelled like cat pee BAD and it only got worse after trying to clean it with water and the shop vac (I’m telling you…the other products didn’t work!) and it didn’t smell like cat pee anymore. She was DUMBFOUNDED.The only downside is during delivery to my home the cap on the gallon jug had been cracked in shipment. Luckily, very little was spilled out and I could still use it.
