Cats can suffer from a variety of wounds, ranging from minor scratches and abrasions to more severe lacerations and punctures. How long it takes for a cat wound to heal depends on several factors, including the location and severity of the injury. In general, cat wounds heal through the same biological process as humans and other mammals.
The healing process involves four overlapping stages: hemostasis, inflammation, proliferation, and maturation. During hemostasis, blood clots form to stop bleeding. Inflammation follows as the body removes damaged tissue and prevents infection. Proliferation involves new tissue formation, and maturation is the final remodeling of scar tissue. Superficial minor wounds may heal within a few days, while more severe or infected wounds can take several weeks or longer to fully resolve.
Proper first aid, wound care, and monitoring are important to support healing. Most minor wounds can heal on their own, but severe, contaminated or non-healing wounds require veterinary care. With appropriate treatment, the vast majority of cat wounds will heal without complication.
Types of Cat Wounds
Cats can suffer from a variety of wounds. Some of the most common types of cat wounds include:
Scratches
Scratches are superficial wounds caused by the claws of another cat or animal. They tend to be narrow and linear. Scratches often occur on the head, neck, and front legs during territorial disputes with other cats. While scratches look benign, they can introduce bacteria deep into the skin and cause infections (1).
Bites
Bite wounds are caused by the teeth of another animal puncturing the skin. Cat bites in particular can be deep and prone to infection since their sharp teeth deliver bacteria deep into tissues. Bite wounds require prompt veterinary care since they have a high risk of abscess formation. Puncture wounds left by individual teeth often drain pus once infected (1).
Abrasions
Abrasions are superficial wounds caused by scraping or rubbing against a rough surface. They remove the outer layers of skin, resulting in a raw, weeping wound bed. Abrasions are common on the paws, belly, and legs. They are prone to getting contaminated with debris and bacteria. Keeping abrasions clean and protected is key to healing.
Lacerations
Lacerations are tears in the skin caused by trauma. They can be straight, jagged, or irregular cuts. Deep lacerations may extend into underlying fat, muscles, or tendons. Lacerations often result from cat fights or accidents. They tend to bleed freely and need veterinary care to properly close the skin flaps (2).

Factors Affecting Healing
There are several key factors that affect how long it takes for a cat wound to heal:
Location
Wounds on the face, legs, and body will heal slower than wounds on the trunk, as there is less blood circulation to the extremities. Wounds on the body also tend to stay cleaner and are less prone to repeated trauma than other locations [1].
Depth
Superficial wounds limited to the epidermis typically heal within 5-7 days. Deeper wounds penetrating into the dermis can take 10-14 days to heal. Severe wounds extending into muscles, tendons or bones can take several weeks or longer to fully heal [2].
Cleaning
Proper cleaning is essential for optimal wound healing. Gently flushing the wound with saline solution keeps it free of debris and bacteria. Bandaging or protective coverings also keep the wound clean. Preventing infection allows healing to progress normally [3].
Healing Stages
There are three main stages that a cat wound goes through during the healing process:
Inflammation – This first stage starts immediately after the injury occurs. Blood vessels at the wound site constrict initially to slow bleeding, then dilate to allow nutrients, enzymes, and cells that fight infection to reach the area. Inflammation triggers the release of histamines and cytokines that help white blood cells clean the wound of debris, bacteria, and damaged tissue. There may be swelling, redness, heat, and pain around the wound during this stage.
Proliferation – In this stage new tissue forms to begin closing the wound. Granulation tissue containing collagen and elastin fibers fills the defect. At the wound edges, epithelial cells migrate across the wound bed to eventually meet and fuse. Blood vessels in nearby tissue branch toward the wound to supply nutrients and oxygen to the healing area. The proliferative phase usually peaks around day 7 but can last a few weeks in some cases. [1]
Maturation – The final stage involves remodeling and strengthening the new tissue. Collagen fibers organize and cross-link for added tensile strength. New blood vessels mature to improve circulation. The wound gradually loses its pink color as it blends with the surrounding skin. Full maturation can take months, but the wound is usually sealed within 1-2 weeks.
Superficial Wounds
Superficial wounds like scratches and abrasions are minor injuries that only affect the top layers of a cat’s skin. These types of wounds will usually heal on their own within 5-10 days (source).
For scratches, the wound will initially look red and swollen as the inflammation phase begins. Within 2-3 days, a scab will start to form over the wound as it enters the proliferation phase. The scab protects the new skin cells and blood vessels forming underneath. Over the next 5-7 days, the scab will get smaller and fall off as the epidermis is restored. Hair around the area may take 1-2 weeks to fully grow back in (source).
Similarly, abrasions caused by scrapes will scab over within 12-24 hours and heal completely within 7 days in most cases. Keeping the wound clean and protected will help speed up the healing. Signs of infection like pus, worsening swelling/redness, or foul odor may indicate a delay in healing.
Intermediate Wounds
Intermediate wounds are moderately deep punctures or tears in the skin that may expose fat, muscle, or bone. These take longer to heal than superficial wounds, usually around 2-4 weeks depending on the location, severity, and aftercare.
For cat bite punctures on the limbs or body, healing can take 2-3 weeks with proper cleaning and bandaging. Facial wounds often heal faster in 1-2 weeks since the face has a robust blood supply.
However, wounds on the legs or paws tend to heal slower, taking 3-4 weeks. These areas don’t have as much blood circulation and are at higher risk of re-injury when the cat walks or scratches.
According to VCA Animal Hospitals, most abscesses from cat bites should heal within 5-7 days with appropriate treatment like antibiotics and draining. The swelling of cellulitis may take longer to resolve.
It’s important to keep intermediate wounds protected and clean during the healing process. Bandages may need regular changing. Your vet can advise on proper cleaning and aftercare for optimal healing.
Severe Wounds
Severe wounds like deep lacerations, puncture wounds, or degloving injuries require immediate veterinary attention and will likely need surgery for proper healing. According to PetMD, deep wounds that expose tissue and involve excessive bleeding should be seen by a vet right away. VCA Hospitals notes these kinds of traumatic wounds are often left open after surgery to heal by second intention, where the wound heals from the bottom up. A drain may be placed to allow fluid and contaminants to escape. The healing time for severe, deep wounds is longer, often 10-14 days according to Joii Pet Care. Kittens also tend to heal faster than older cats. It’s important to properly clean and monitor these major wounds, provide pain medication per the vet’s instructions, and restrict activity to prevent reinjury.

Monitoring Healing
It’s important to closely monitor your cat’s wound for signs of proper healing or potential complications. Check the wound at least twice a day. Signs of proper healing include the wound edges drawing closer together, pink healthy tissue developing around the wound, and any stitches remaining intact without swelling or redness. The wound should also be free of discharge or foul odor.
Potential complications to look out for include increased swelling, redness, pain, or discharge around the wound. The cat may seem more lethargic than normal. You may also notice reduced appetite. These can be signs of infection. Excessive licking can reopen the wound or introduce bacteria. Any discharge from the wound should be yellowish rather than green or foul-smelling. Please consult your vet immediately if you notice any of these warning signs, as antibiotics or additional treatment may be required. Monitor the wound until it is fully closed over with fresh skin.
It’s important not to disturb or handle the wound unless necessary during the healing process. Allow any bandages to remain in place for the recommended period of time. Check that your cat is not chewing at sutures or bandages. Restrict activity and make sure your cat does not leap up on furniture or play roughly, to avoid re-injuring the area. With diligent monitoring and proper aftercare, most minor to moderate wounds should heal within 1-2 weeks.
Aftercare
Proper aftercare is crucial for helping wounds heal and preventing infection. The wound should be gently cleaned at least 2-3 times per day with a mild antiseptic solution like diluted chlorhexidine or povidone iodine and warm water to remove any discharge or debris (VCA Hospitals). Take care not to scrub hard or irritate the wound. Pat dry with a clean towel after cleaning. An antibiotic ointment like Neosporin can be applied sparingly after cleaning to promote healing and fight infection.
It’s important to monitor the wound for signs of infection like redness, swelling, heat, oozing pus, foul odor and fever. Cleaning diligently helps prevent infection by removing bacteria before it can multiply (PetMD). If signs of infection develop, promptly contact your veterinarian for examination and antibiotic treatment. Allowing the wound to heal uncovered helps prevent infection, so bandages should only be used at the direction of a veterinarian.
Restricting activity aids healing by preventing re-injury. Providing nutritional support with a high quality diet also optimizes wound healing. Follow all aftercare directions from your veterinarian closely to ensure proper healing.
When to See the Vet
Most minor wounds can heal on their own, but it’s important to monitor your cat for any signs of complications or infections that require veterinary care. According to Hope Crossing Animal Hospital, you should take your cat to the vet if:
- The wound is deep, gaping, or longer than 1 inch
- There is significant bleeding that won’t stop
- Any body parts like muscle or bone are exposed
- There are signs of infection like redness, swelling, pus, foul odor, or your cat has a fever
- Your cat seems to be in severe pain or distress
- The wound doesn’t seem to be healing properly after a week
Veterinary care is crucial for serious wounds to properly clean, stitch, bandage, prescribe antibiotics, and monitor the healing process. An untreated infected wound can have devastating consequences for a cat’s health. It’s always better to err on the side of caution and have a vet examine any questionable wounds on your cat.
