There are a variety of disinfectants that are sold for use on pet wounds. The most common are povidone-iodine and chlorhexidine. Consult with your veterinarian if you want to have one of these products on hand if your cat gets scratched up.  Remember, not all disinfectants are safe for cats. Those contained phenol are toxic to felines. Read the label to see if the product is a phenolic disinfectant, and avoid using if it is. Another sign the product contains phenol is if it goes cloudy when water is added. If in doubt, avoid and use an alternative. To use povidone-Iodine dilute it by mixing 1 ml of povidone-iodine with 100 ml of water. Use this solution to wash away contamination from the surface of the wound. To use chlorhexidine mix 2.5ml of chlorhexidine with 100 ml of water to make the correct strength to clean a wound. Chlorhexidine is the active constituent in many surgical scrubs, such as Hibiscrub. It is a pink soapy solution that needs to be diluted in water. Chlorhexidine has good antibacterial properties and also has a slight residual action, which means it keeps on working at killing bacteria for a while after it has dried. Another popular wound cleansing agent is hydrogen peroxide. However, this has the potential to be very damaging to tissue if used undiluted. The 'myth' is that the fizzing as the peroxide contacts the wounds is simply killing the bacteria, but unfortunately it is also damaging the tissue bed, which needs to be healthy for future healing. The correct dilution is to take a 3% solution of hydrogen peroxide and mix one part peroxide with three parts water (for example 25 ml of peroxide with 75ml of water) to make a disinfectant solution that is suitable for cleaning wounds. The disinfectant to use is a matter of personal preference and what you have available. Always follow the instructions on how to dilute the product, because using it too concentrated can be damaging to tissue. Be aware that many household disinfectants and some disinfectant sprays contain benzalkonium chloride...
