If the pet licked a bowl with sharp edges or gnawed bones, it is fraught with damage to the soft tissues of the bottom lip, wounds can be found during examination. The animal can damage the lip in a fight or during a game, especially if it goes outside or contacts with other animals.

You can see the constant salivation and bad breath of the animal, lack of appetite due to pain. This disease occurs in acute form or is chronic. That is often a consequence of serious health problems in cats (hepatic or renal failure, diabetes mellitus). Gingivitis requires urgent treatment, the inaction of the owner results in the loss of the pet’s teeth.
  7. Fungal stomatitis occurs due to a decrease in the immune system of the body or long-term treatment with certain types of drugs. It is characterized by a white plaque in the oral cavity, which causes a strong inflammatory process.
  8. Eosinophilic granuloma-an allergic reaction to the components of the diet or insect bites of different species. It manifests itself directly in the oral cavity, affecting the lips and mucous membranes. It is possible to define it by tumors of the bottom lip, dark pink hue and bright, small bubbles. Externally, the picture is similar to the initial stage of herpes in humans. In this disease it is important to determine the allergen and to provide the animal with the full course of treatment.

In this case, the tumor from the lip will subside on its own, but it is worth paying attention to how often the cat has this problem. In a single case, do not worry, but if rashes appear systematically, it is necessary to find out the cause and conduct a course of treatment for the pet.
