A pressure ulcer, also known as a bedsore or pressure sore, is a localized injury to the skin and/or underlying tissue that usually occurs over a bony prominence as a result of pressure, or pressure in combination with shear and/or friction. Pressure ulcers can develop when a person remains in one position for an extended period of time, leading to reduced blood flow to the area and tissue damage. They are a common problem for individuals with limited mobility and can range in severity from mild redness to open wounds that extend through the skin and into the underlying tissue. **

It is important to seek veterinary care if you suspect your cat may have a corneal ulcer, as prompt treatment is necessary to prevent further complications and promote healing. **

A pressure ulcer, also known as a bedsore, is a localized injury to the skin and/or underlying tissue usually over a bony prominence, as a result of pressure or pressure in combination with shear. It is important to consider the location of the injury, the patient's risk factors, and the appearance of the wound. If the injury is located over a bony prominence, the patient has limited mobility, and the wound appears as a shallow or deep crater, it could be a pressure ulcer.
