To eliminate the pet odors, simply clear all of your pets from the area, and close it off completely. Start the ozone generator and run it for several continuous hours depending on how severe the odor is. When the generator makes contact with the odor, it will eliminate it right from the source. Depending on the severity of the odor, a window may need to be cracked open to allow a source of fresh air to circulate along with the generator.
Once you feel that the ozone generator has done its job, leave the room for about an hour. This will allow the generator to dissipate for awhile. If the pet odors have not been completely eliminated, continue the cycle once more to ensure that the odors are gone. If your pet is consistent in this area, you may need to repeat the process from time to time if you should notice an odor.
