Why does my cat have a hole in her side?

If your cat has a hole in her side, it is most commonly a sign of an abscess that has ruptured. This condition requires prompt veterinary attention.

Understanding Abscesses in Cats

An abscess is a localized collection of pus within the body's tissues, typically caused by a bacterial infection. In cats, these are often the result of an injury, such as a bite wound from a fight with another animal.

What Causes a Hole (Ruptured Abscess)?

When a cat gets into a scuffle, especially with another cat, a bite or scratch can introduce bacteria deep under the skin. The small puncture wound often seals over quickly, trapping the bacteria inside. The body then forms an infection, leading to:

• Swelling: A firm, painful lump develops as pus accumulates.
• Pain: The affected area becomes tender to the touch.
• Heat: The skin over the abscess may feel warmer than surrounding tissue.

Over time, as the infection progresses, the pressure inside the abscess builds. Eventually, the skin covering the abscess breaks open, creating an open, gaping hole from which pus and fluid drain. This draining provides relief from the pressure but signifies an active infection that needs to be treated.

Common Scenarios Leading to Abscesses:

• Cat Fights: This is a very common cause, as feline teeth and claws can easily puncture the skin and introduce bacteria. Abscesses frequently occur on the head, neck, limbs, or at the base of the tail where bites are common.
• Other Injuries: Any skin puncture or deep wound that gets infected can lead to an abscess.
• Foreign Objects: Splinters or other foreign bodies embedded under the skin can also trigger an infection and abscess formation.

What to Do If Your Cat Has a Hole in Her Side

Discovering a hole in your cat's side, especially if it's broken, oozing, or smells, indicates a serious underlying issue that needs professional medical care.

Immediate Steps:

1. Contact Your Veterinarian Immediately: Do not attempt to treat the wound at home. A veterinarian needs to thoroughly examine the area.
2. Prevent Licking: Try to prevent your cat from licking or biting the wound, as this can introduce more bacteria or hinder healing. An Elizabethan collar (e-collar) may be necessary.
3. Observe Your Cat: Note any other symptoms, such as lethargy, fever, loss of appetite, or limping.

Veterinary Treatment Typically Involves:

• Cleaning and Draining: The vet will thoroughly clean the wound, remove any remaining pus, and ensure proper drainage.
• Antibiotics: Oral or injectable antibiotics are crucial to combat the bacterial infection.
• Pain Management: Pain medication will be prescribed to keep your cat comfortable during recovery.
• Follow-Up Care: You may need to clean the wound at home and administer medication as directed by your vet.
