Cat bite abscesses
If you notice small lumps or swellings when stroking or brushing your cat do not be unduly alarmed. There are many possible causes: growths, cancers, infections, allergic reactions to flea bites or foreign bodies such as thorns or airgun pellets. Occasionally your cat may pick up ticks that swell up as they feed on cat's blood and can easily be mistaken for a skin lump. However, the most likely cause of a lump in your cat is an abscess.
