Pros: None. Product does not work as advertised.
Cons: Product is NOT formulated as indicated on the label. Does NOT contain bacteria or enzymes.
As a long-time cat owner who has used various cat urine remover products over the years, I have noticed that the majority of pet stain products on the market today seem to rely on heavy perfumes to cover up pet smells instead of actually neutralizing the organic base of the stains.
After using PetZyme repeatedly to try to remove cat urine in my house with no success, I finally began to wonder just what ingredients were in the product that did not work. The "Active Ingredients" on the label states: Friendly bacteria, enzymes and a mild surfactant.
Because the bacteria and enzymes were not identified, I looked up the MSDS (Material Safety Data Sheet) for PetZyme, which the manufacturer is legally obligated to provide, and FOUND THERE ARE NO BACTERIA AND NO ENZYMES IN THIS PRODUCT. In short, the manufacturer's claims of "All natural enzyme formula" on the label are pure marketing--and a lie.
What are the real ingredients? 1,8-P-menthadiene, a perfume agent, and 2-butoxy ethanol, isopropyl alcohol, and propane/N-Butane, all volatilizer agents. NO NATURAL BACTERIA OR ENZYMES ARE IN THIS PRODUCT AS CLAIMED.
The MSDS sheet for PetZyme can be found at http://www.competitivechoice.net/ccch/pdfs/230msds.pdf.
I am angry that I have wasted a considerable amount of money and time using this product trying to neutralize cat urine in my house when this product was never formulated to do the job it is advertised to do in the first place.
