How to Clean a Cat's Wound

Purchase a sterile saline solution. A sterile saline solution (like the kind typically found in first aid kits) is the ideal choice for cleaning contaminated wounds. The cleaning process helps remove bacteria and dirt particles, and the saline’s pH level, similar to that of body tissues, helps minimize tissue damage.

• You’ll need to use a generous amount of saline solution and continue cleaning until the wound looks clean.

Boil water and let it cool before cleaning the wound. For dirty wounds filled with dirt and grit, you can use boiled and cooled water as an alternative to saline solution to clean the wound.

• There is a slight risk of causing tissue damage when using water instead of saline: Water lacks the components found in body fluids, so it can draw out fluids from the damaged tissues when it comes in contact with them. However, medical research has shown that using tap water to clean wounds does not significantly affect the risk of infection.

Prepare a saline solution. Saline solution has natural antiseptic properties and is an excellent solution for cleaning wounds on cats. To prepare saline, boil a kettle of water, measure 1 cup of water, and add half a teaspoon of salt. Stir until the salt dissolves and let it cool.

• The saline you just made is also similar to tears and body fluids, so it’s gentler on tissues compared to commercial antiseptic solutions or plain water.

Purchase a pet-safe antiseptic solution. There are several antiseptics available for cleaning wounds on pets, with povidone-iodine and chlorhexidine being the most common. Consult your veterinarian if you wish to buy one of these products to keep on hand in case your cat gets scratched.

• Not all antiseptics are safe for cats. Products containing phenol can be toxic to felines. Be sure to check the label for phenol content. If the solution becomes cloudy when water is added, it likely contains phenol. If in doubt, avoid using the product and choose another.
• For povidone-iodine: dilute 1 ml of povidone-iodine with 100 ml of water. Use the diluted solution to clean impurities from the wound.
• For chlorhexidine: mix 2.5 ml of chlorhexidine with 100 ml of water to achieve the correct concentration for wound cleaning. Chlorhexidine is a common antiseptic in surgical cleaning products, such as Hibiscrub. It’s a pink-colored soap solution that needs to be diluted with water. Chlorhexidine has strong antibacterial properties and is effective even after it has dried.

Dilute hydrogen peroxide. Hydrogen peroxide is another common wound cleaning solution. However, this solution can be very harmful to tissues if not diluted. The bubbling when hydrogen peroxide contacts a wound indicates that bacteria are being killed, but unfortunately, it also damages healthy tissues that are essential for healing.

• The correct dilution is to mix 1 part 3% hydrogen peroxide with 3 parts water (for example, 25 ml of hydrogen peroxide with 75 ml of water) to create an appropriate disinfecting solution for wound cleaning.

Select the safest product available. The choice of disinfectant solution depends on your preference and what you have on hand. Always follow the dilution instructions on the product, as too concentrated a solution can harm tissues. Note that many household disinfectants and some spray disinfectants containing benzalkonium chloride are not formulated for use on living tissues.

• If you're unsure whether a particular disinfectant is safe for cats, it is best to use a salt solution or saline, which is always a safe option.

Ask someone else to help hold your cat. Your cat is likely in pain or shock after being injured and may scratch or bite when you touch the injured area. This is true even for typically calm cats. Therefore, you should ask a friend or neighbor to help hold the cat so you can focus on cleaning the wound.

• Try wrapping the cat in a large towel, leaving only the wound exposed. This method can help calm the cat and reduce the risk of being scratched or bitten.

Clean the wound using a syringe. Pour the wound cleaning solution of your choice into a bowl. Use a syringe to draw the solution and spray it onto the wound to clean and disinfect it. Spray the wound multiple times until it feels clean.

• New wounds should be cleaned and disinfected to reduce the risk of infection.
• Scrapes from incidents like being hit by a vehicle or falling from a tree can get contaminated with dirt and bacteria. Proper cleaning to remove debris can reduce the risk of complications, such as infections or slow healing.

Use cotton balls soaked in solution to clean the wound if you don't have a syringe. If a syringe is unavailable, you can soak cotton balls in the solution and squeeze them onto the wound. If the wound is very dirty and this method doesn't remove debris, you can gently dab the cotton ball on the wound to clean it.

• After each dab, use a fresh cotton ball to avoid re-contaminating the wound. Continue cleaning until the cotton ball no longer comes away dirty, then rinse the wound with the solution.
• If the cat has an abscess, the wound might leak pus. Use cotton, gauze, or tissue to absorb the pus. Gently press around the abscess to encourage the pus to drain out. It's important to clean out as much pus as possible, as it is a source of ongoing infection.

Apply disinfectant. You can use a disinfectant after thoroughly cleaning the dirt. Follow the instructions on the packaging for correct usage.

• The goal here is to cleanse the infected area until you see healthy tissue, free of contaminants, before applying the disinfectant.

Determine if the wound needs to be bandaged. Most wounds should be exposed to air, so avoid covering small, minor injuries. However, if your cat keeps licking or biting at the wound, you should cover it. In such cases, the wound may take longer to heal.

• Some believe that licking wounds is beneficial for cats, but in reality, their rough tongues can damage tissues rather than promote healing.

Observe your cat for signs of injury. It's crucial for cat owners to understand their cat's normal behavior. This awareness will help you detect if something is wrong. Watch for changes in behavior, including (but not limited to) alterations in eating habits, movement, and communication.

• Such changes could be indicators of various illnesses, including injuries.
• If your cat's behavior or temperament changes suddenly and without explanation, take it to the vet. These changes might signal a health problem.

Check for wounds if you hear or see your cat fighting. If you hear a cat fight or notice your cat limping when it returns home, inspect your cat for signs of injury. One indicator of a fight is clumps of fur stuck together. Look for areas where the fur appears matted or stands up at an unusual angle. Gently part the fur and examine the underlying skin.

• You may also find bald spots where your cat's opponent pulled fur during the fight. These areas could be wounded. You might also observe bleeding or swelling. Cats with white or light-colored fur are easier to check for injuries. For black cats, gently stroke the cat's body and watch for signs of pain or sensitivity, indicating wounds, swelling, or scabs.

Regularly check your cat for injuries. You won’t always see your cat fighting or notice signs of wounds on its fur. That’s why it’s important to routinely inspect your cat for injuries. This is especially crucial if your cat frequently goes outside and engages in fights.

• Grooming your cat is a perfect opportunity for this. Keep the cat calm, gently stroke its body, and carefully examine the skin beneath its fur.
• Old wounds might become infected, presenting symptoms like swelling, scabbing, fur loss, and oozing blood or pus.
• Old abscesses that rupture can leak pus, causing the fur to mat together.
• Additionally, the skin over an abscess can die, leaving a large hole where underlying muscles or tissues may be visible.

• Minor wounds can be cleaned at home while monitoring for signs of infection. However, larger or deeper wounds that penetrate the skin or expose underlying tissues need to be treated by a veterinarian. You should also take your cat to the vet if there’s a puncture wound near any joints, as bacteria can enter the joint, and a short course of antibiotics may be necessary to prevent septic arthritis.
