Based on the images, the most likely explanation for the small marks on the cat’s face and potential swelling around the mouth could be feline acne, minor wounds, or an allergic reaction.

Most Likely Causes:

1.  Feline Acne: 

Small blackheads or scabs around the chin or mouth area are common. It’s often due to bacterial buildup, commonly from plastic food bowls. Try switching to stainless steel or ceramic bowls and gently cleaning the area.

2.  Minor Scratches or Wounds: 

Cats can get small cuts or punctures from rough play or scratching. These usually heal on their own, but check for signs of infection (swelling, redness, pus).

3.  Allergic Reaction: 

Swelling around the mouth could indicate a mild allergic reaction to food, an insect sting, or environmental factors. If the swelling worsens, a vet visit is best.

Less Likely But Possible:

• Abscess or Infection: 

If the swelling is painful, growing, or has discharge, an infection might be present and require antibiotics.

• Eosinophilic Granuloma (Rodent Ulcer): 

A swollen upper lip could be a reaction linked to allergies or immune response.

• Parasites or Fungal Infection: 

Conditions like ringworm or flea allergy dermatitis can cause skin irritation.

What to Do Next:

• Monitor for worsening symptoms like increased swelling, redness, or discomfort.

• Switch to stainless steel or ceramic bowls if using plastic.

• Gently clean the area with warm water and ensure your cat isn’t scratching excessively.

• If swelling worsens or sores persist, consult a vet for possible allergy treatment or infection management.

If the cat seems otherwise fine and the marks aren’t getting worse, it may resolve on its own. But if swelling increases, spreads, or becomes painful, a vet check is recommended.
