How to keep the cages, kennels, dog runs, litter boxes, and othe spaces clean, sanitized, and disinfected without harming both the animals and the caregivers is a real dilemma. Unfortunately, our veterinarians tell us that most pet deaths are premature and unnecessary .
The best answer yet has been to remove pets from their enclosures, wash down thoroughly their habitat, clean away all other debris and treat the space with some pretty nasty (often expensive) chemicals. 
After which, washing down everything and hoping there is no residual dangerous contamination lingering from either pathogens or the disinfectant is the best one can do. The problem is that disinfectants are mostly toxic, and most good disinfectants are not safe to use around pets, period.
The newest approach involves the use of Stabilized Chlorine Dioxide.Chlorine Dioxide is truly a remarkable substance.
Broad Spectrum Disinfectant Nok-Out has as a main ingredient, proven to destroy many bacteria and viruses (even parvo), it is one of the fastest acting broad spectrum disinfectants!
It is difficult to get the performance from other products while still having safety for pets who may be sensitive to more toxic chemicals. It kills bacteria, viruses and fungi, while remaining an extremely powerful deodorizer. Nok-Out destroys all pathogens of significance that are harmful to us, our pets, and our environment. Animal habitats, enclosures, and cages should be cleaned with water and soap to remove debris and other solids; then apply Nok-Out by spraying on the Source of the Odors. This provides both sanitizing and deodorizing properties of stabilized chlorine dioxide.
The chemistry of Chlorine Dioxide is radically different from that of chlorine itself. Technically speaking, both are oxidizing agents. Chlorine and Chlorine Dioxide are distinctly different in that they do not react in the same ways with organic compounds and generate very different byproducts. Chlorine tends to react with organic matter by attackiing cell walls and creating byproducts, some of which are toxic and carcinogenic, whereas chlorine dioxide does not affct cell walls (which is why it is safe to use around living things.) Chlorine Dioxide disassembles organic compounds rendering them harmless. It is this difference that explains the superior performance of chlorine dioxide.
The anti-microbial efficacy of chlorine dioxide against bacteria, fungi, viruses and protozoa has been repeatedly demonstrated and documented. It has a low toxicity, as verified by the EPA, is not harsh to you, the environment, or your pets.Along with being a powerful disinfectant, chlorine dioxide is also a natural anti-inflammatory, making it useful for wound treatment. Veterinarians are using a chlorine dioxide gel mixed with aloe vera to treat incisions and wounds.
Nok-Out is the one true deodorizer for pet owners, one which will eliminate odor, protect the environment, and cause no harm to the owner or his pets.This product is registered by the EPA to be safe, harmless to pets and people, hypoallergenic, biodegradable, non-staining, non-bleaching, You have selected the best product on the market for you and your pet.
