Mister Max Anti Icky Poo Pet Urine Enzyme Cleaner & Feces Odor Remover, Enzymatic Cleaner for Dog & Cat Urine, Pet Odor Remover Spray, 1 Gallon (Unscented)

As someone with a major cat urine problem and have gone through gallons of this stuff, I thought it’d be helpful to leave a realistic review and share my story. I recently moved to a different apartment and the previous tenants had a cat. There was tons of cat hair around the apartment and wasn’t very clean overall, but I figured “no big deal, I’ll just clean it up and it’ll be like new” (spoiler: wasn’t the case at all). Another thing to mention is the carpet was replaced in the whole unit, except ONE room. I didn’t think much of it at the time because that’s a pretty normal thing in between tenants, but more on that later. Now, I’m not sure what sort of magic the landlord did while I was touring the apartment, as there was no smell of cat urine - at all. Didn’t even cross my mind. I move in a little bit later and everything is fine. Fast forward a few days and I notice a smell in the one bedroom where the carpet WASN’T replaced. I noticed my own cat was acting a little strange and sure enough I discovered he peed on the floor. Very foolish me at the time thought this was it, and having no knowledge on cat pee, I grabbed my carpet shampooer and shampooed the section of carpet where he peed. While I was at it, I figured, “Why not just shampoo this whole room?” Sure enough, that made it worse. This is when I went full detective mode on my hands and knees smelling every inch of the carpet while my cat is staring at me wondering wtf I’m doing. I quickly realized the smell extended far beyond where my own cat had peed. I ran to the internet and began researching the topic of Cat Urine as if I was writing a thesis on it. This is when I learned that when cat urine is rewetted, it reactivates uric acid to recrystallize and suddenly made sense as to why this entire room now reeks of cat urine - I just wetted the entire carpet with the shampooer. Two corners of this room in particular smelled extra terrible, and at this point there was no way my cat did of all of this on his own. I resorted to pulling up about a foot of the carpet and was instantly hit with the most rancid, stale, rotten cat urine smell. The entire carpet pad was stained, the entire subfloor was stained, it seriously was AWFUL. At this point, I connected the dots: the previous tenants had a SERIOUS cat pee problem, hence why the carpet was replaced. I went around the unit and smelled nearly every corner in the unit and another 3 corners smelled just as bad on the wall and baseboards in the rooms where the carpet WAS replaced. No idea why the last bedroom didn't get it's carpet replaced too, but it was obvious at this point there was a major problem, and if I owned the place, I’d be ripping out the carpet in the last bedroom. However, that isn’t an option, so I resorted to finding a solution that would work for now. The biggest takeaway is you need one very key ingredient to get rid of the problem: Enzymes There’s tons of enzyme cleaners. I started with Rocco & Roxie and the fragrance nearly took me out. Probably would have worked if I used enough, but only used 32 oz of it - not nearly enough and didn’t want to buy more because of the intense fragrance. I tried Skout’s Honor because of good reviews and realized once I got home it’s not even an enzyme cleaner. Sure enough, didn’t work. This leads me to Anti Icky Poo, and thankfully I think this will be my last product. (And HUGE bonus is that it comes in an unscented version - definitely recommend that version) One really important thing to point out is you need to follow the instructions, especially for major urine problems. It says right on the bottle you’ll need at least a quart for 1 corner and multiple applications may be necessary. Acknowledge this step! For me, this equated to needing literally GALLONS of this. The key to this product is absolutely dousing the affected area and letting it stay soaked. In my case, I poured about a gallon on one corner, let it sit for a whole day with trash bags on top to preventing it from evaporating, and after drying it was probably 95% better! Realistically, I’m sure there will always be some odor in this case due to the subfloor being stained with the urine. It’s not a miracle product that will suddenly replace your subfloors soaked with years of cat pee - it just does what it says. This was clearly a problem that is too long gone at this point and likely needs complete replacement of subflooring. But, like I said, this isn’t an option, so I believe this product dealt with my issue in the best way given the circumstances. Maybe at some point I'll buy some more, pull up the carpet, and try soaking the subflooring, but thankfully, the room no longer smells like cat urine, and the only way you even get any hint of a smell is if you stick your nose directly in the corner. Overall, this product is really great. It does exactly what it says it’s going to. It didn’t rip out my subflooring and replace it, but it doesn’t claim to. There’s obviously physical limitations to a liquid product. But for most issues, this will do what it claims to do. Just don’t spritz your carpet with a decade of cat pee embedded into it and expect it to work, you really have to use it very liberally.

I have been searching for a good product that actually gets rid of the smell of cat urine rather than masking it, and my search is over. I actually discovered this product using an AI search. This stuff works! And yes it works on old urine odors and hot pet pee spots on old carpet! When you have five cats, especially ones who find other places to pee other than a litter box things can get rather aromatic in a negative way. This stuff gets rid of the smell! My house no longer smells like aged ripe cat pee. It is easy to use and it leaves behind a refreshing minty scent that soon fades into nothing. No smell at all, not from the cleaner or the urine. I will remain a loyal customer.

This works better than any other enzyme cleaner I've tried, and yes, I've tried all of them. I use the scented version of this, which is nice, and the strong-to-me scent fades rather quickly. I have four cats, two of which have territorial issues, and this stuff helps with the cleanup better than any other. I didn't have any faith when I ordered it, and it's a bit pricey, but it works, and that's what matters. I mix it half-and-half with water for a litter area spray as a general "blue light" cleanup. I won't bother with anything else.

This stuff is pretty great if you follow the instructions. It's not cheap, but if you want to make sure the ammonia smell doesn't take hold in your carpet, this stuff is fantastic. I actually ended up using this on both an old urine spot and a new one. The new ones I got to right away, but they still left a bit of a stain on the carpet. The smell however was completely taken away. As soon as you pour this on the carpet the smell begins to improve. It helps a lot if you use the method of "injecting" it into the carpet to get below the surface. I did not purchase a carpet syringe from them but instead just used a needleless syringe I had lying around. It possibly wasn't AS effective as a carpet syringe from this company, but it got the job done. Seeing as how I applied this product (following the directions) on a fresh spot (no yellowing had taken place yet), I sort of thought it would help prevent staining but it did not, so I took off 1 star for that. On the old stain, I had to put down a couple applications but in the end, the smell did improve. The stain did not. I was not expecting stain removal from this product on an older stain though so that was okay. This was a favorite urinating spot for one of my cats for probably a couple years. Only recently did she stop going there. Because she finally stopped going there, I decided to really make a concerted effort to get ALL the smell out and this stuff did great. The smell would get out of control when the house was warmer, and now we don't even notice it. I still have a little work to do on it, as you can still smell it a little if you put your nose close to the carpet, but it is vastly improved. I think I just need to get the product to the padding underneath the carpet and we'll be good. Overall, I'd highly recommend this product. It works on old odors and new, and does a great job of it. It works far better than anything else I've ever tried on old urine odors. Just don't expect any stain removal/prevention properties from this. I will eventually probably try their special stain removal product, considering how happy I am with this in terms of odor removal.

This product is WONDERFUL. it has saved me from re-carpeting my home. It actually works. Great. Cannot recommend it more highly.

I have a 14 year old cat that spends a lot of time outside in the summer. But come winter it is too cold for his liking. However, he is used to having the whole back yard as a litter box and does not like to be confined to a box (he has good days and bad days). So he will sometimes use the stairs or floor instead. It's purely a behavioural thing and the vet says he is healthy. So, knowing he is healthy, we searched for ways to curb this behaviour with bigger litter boxes and more of them and in places he frequents. The last step was to remove the enzymes from previous "accidents" with this Anti Icky Poo. I like this stuff a lot. There is zero smell (I got the unscented stuff). I checked with a black light after clean up and everything was gone (I have no carpets). It has reduced the amount of times he has used the stairs and floor significantly (not entirely because it is behavioural and that is on him not the product). But definitely a noticeable difference. I went from having to clean up 4 - 6 times a day to maybe once every other day or so now. Did my whole house, upstairs and down with one jug and still have a bit left over. If I run into the same problem next winter, I will be buying this again next year.

My cat trashed two counches by weeing and poohing on them so was desparate to find a product to remedy the situation. This product worked after many applications as the stains were very bad. Its expensive but it works.

WHAT ABSOLUTE MAGICAL product !!!!!! I’m amazed. Believe me I tried EVERYTHING on the carpet because my dog pooped on it couples of times when I wasn’t home and it’s a fluffy expensive carpet and I wanted to take the odour out. Nothing worked. BUT THIS ???????? He ahaha not pooped there since. It does not smell anything he doesn’t even sniff there since. The product smells great at first and then the odour disappears. It takes about an hour to dry completely.

We tried countless enzymatic sprays for cat urine and this is the only one that does the trick!
