Basics and possible causes
The oralOral means "through the mouth" and refers to the intake of food, medication, or other substances through the mouth. In veterinary medicine, many treatments are administered orally. mucosaMucosa, also called mucous membrane, refers to the moist lining of body cavities that are connected to the outside world, such as the mouth, nose, lungs, and gastrointestinal tract. It serves to protect and facilitate the absorption of nutrients. is rich in blood vessels and can easily react to injuries or systemic health problems. EcchymosesEcchymoses are flat Bleeding under the skin or mucous membrane, caused by blood leaking from the vessels.

Platelets and certain proteins in the plasma form a blood clot that seals the wound., and a deficiencyDeficiency means a lack or absence of a necessary substance required for normal bodily functions or health, such as vitamins, minerals, or hormones. can lead to spontaneous bleeding. ThrombocytopeniaThrombocytopenia is a condition in which the number of platelets in the blood is lower than normal, increasing the risk of mild to severe Bleeding. can be caused by infections, autoimmune diseasesAutoimmune diseases are conditions in which the immune system mistakenly attacks the body's own cells or tissues as if they were foreign substances. Examples in dogs and cats include autoimmune hemolytic anemia and systemic lupus erythematosus., or certain medications.
Another possible cause is a coagulopathyCoagulopathy refers to a blood coagulation disorder that can lead to an increased tendency to bleed or excessive clotting. Causes can include genetic factors, diseases, certain medications, or liver dysfunction., where the normal clotting function of the blood is disrupted. This can be genetic, as in hemophilia, or acquired, for example, through liver disease that impairs the production of coagulation factorsCoagulation factors are proteins in the blood that are essential for blood coagulation. They work together to stop Bleeding by forming a blood clot. Disorders or deficiencies in coagulation factors can lead to bleeding problems in dogs and cats.. A vitaminVitamins are organic compounds that are necessary in small amounts for the normal growth, development, and physiological function of the body. Vitamins must mostly be obtained through food, as the body cannot produce them or not in sufficient quantities. K deficiencyDeficiency means a lack or absence of a necessary substance required for normal bodily functions or health, such as vitamins, minerals, or hormones. can also impair blood coagulationBlood coagulation is a process that helps stop Bleeding when a blood vessel is damaged. Platelets and certain proteins in the plasma form a blood clot that seals the wound..
VasculitisVasculitis is the inflammation of blood vessels, leading to changes in the vessel walls, including thickening, weakening, narrowing, and sometimes the formation of aneurysms or blood clots., an inflammation of the blood vessels, can also cause ecchymosesEcchymoses are flat Bleeding under the skin or mucous membrane, caused by blood leaking from the vessels. They are often visible as blue or purple spots and can occur after injuries or with certain medical conditions.. This inflammation can be triggered by infections, allergies, or autoimmune processes. The inflammation weakens the vessel walls, allowing blood to leak into the surrounding tissue.
Finally, toxicToxic means "poisonous" and refers to substances that can have harmful effects on the body, including damage to organs, cells, or disruption of metabolic processes. substances, such as certain plants or chemicals, can disrupt blood coagulationBlood coagulation is a process that helps stop Bleeding when a blood vessel is damaged.

When to see a vet?
A visit to the vet is urgently required if you notice purple spots in your cat’s oralOral means "through the mouth" and refers to the intake of food, medication, or other substances through the mouth. In veterinary medicine, many treatments are administered orally. mucosaMucosa, also called mucous membrane, refers to the moist lining of body cavities that are connected to the outside world, such as the mouth, nose, lungs, and gastrointestinal tract. It serves to protect and facilitate the absorption of nutrients., as this can indicate a potentially serious illness. If left untreated, the underlying causes can lead to severe complications or even death.
Especially if the cat also shows other symptoms such as lethargy, pallor, loss of appetite, or unusual bleeding, it should be presented to a veterinarian as soon as possible. These symptoms can indicate a systemic disease that requires immediate medical attention.
A veterinarian should also be consulted if the cat shows signs of pain or behavioral changes. These signs can indicate discomfort or pain that needs to be treated to ensure the cat’s well-being.
Symptom recognition for the pet owner and veterinary diagnostic procedure
For the pet owner, recognizing purple spots in the oralOral means "through the mouth" and refers to the intake of food, medication, or other substances through the mouth. In veterinary medicine, many treatments are administered orally. mucosaMucosa, also called mucous membrane, refers to the moist lining of body cavities that are connected to the outside world, such as the mouth, nose, lungs, and gastrointestinal tract. It serves to protect and facilitate the absorption of nutrients. is often the first indicationIndication refers to a valid reason or rationale for using a specific treatment, medication, or medical procedure. It is based on the diagnosis and the patient's clinical condition. of a problem. Regular inspection of the oralOral means "through the mouth" and refers to the intake of food, medication, or other substances through the mouth. In veterinary medicine, many treatments are administered orally. mucosaMucosa, also called mucous membrane, refers to the moist lining of body cavities that are connected to the outside world, such as the mouth, nose, lungs, and gastrointestinal tract. It serves to protect and facilitate the absorption of nutrients. can help detect such changes early. You should look for discoloration, swelling, or bleeding.
To make a diagnosis, the veterinarian will perform a thorough clinical examination, including an inspection of the entire oralOral means "through the mouth" and refers to the intake of food, medication, or other substances through the mouth. In veterinary medicine, many treatments are administered orally. cavity and a general physical exam. Blood tests are crucial to check the number of plateletsPlatelets, also called thrombocytes, are cells in the blood that play a crucial role in blood coagulation. They help stop Bleeding by forming clots that seal injuries in blood vessels., the blood’s ability to clot, and the cat’s overall health.
Further diagnostic tests may be necessary to determine the cause of the ecchymoses. These include tests for infectiousInfectious describes the ability of a pathogen to be transmitted from one individual to another and trigger an infection. It also refers to diseases caused by such pathogens. diseases, liver function tests, and possibly imaging procedures such as ultrasoundUltrasound refers to sound waves that are above the hearing threshold of the human ear. In medicine, ultrasound is used for diagnostic imaging procedures to visualize internal organs, tissues, and blood flow. or X-rayX-ray is an imaging technique that uses X-rays to create images of the inside of the body. It is often used to diagnose bone fractures, lung diseases, and other conditions. to look for signs of internal bleeding or other abnormalities.
In some cases, a biopsyA biopsy is a medical procedure in which a small amount of tissue is removed from the body to be examined under a microscope for signs of disease. Biopsies can help diagnose cancer and other conditions. of the affected mucosal areas may be performed to rule out inflammatory or neoplastic processes. This can help diagnose specific causes such as vasculitisVasculitis is the inflammation of blood vessels, leading to changes in the vessel walls, including thickening, weakening, narrowing, and sometimes the formation of aneurysms or blood clots. or tumors.
What the pet owner can do and professional therapy options
As a first step, the pet owner should ensure that the cat is not exposed to further stress or injuries that could worsen the bleeding. A calm and safe environment can help lower the cat’s stressStress refers to the state of an organism reacting to external stimuli or demands. In veterinary medicine, stress can have physical or psychological effects on animals, impacting their health and well-being. levels and prevent further bleeding.
It is important to keep the cat away from potential toxins that could affect blood coagulationBlood coagulation is a process that helps stop Bleeding when a blood vessel is damaged. Platelets and certain proteins in the plasma form a blood clot that seals the wound.. This includes ensuring the cat does not have access to poisonous plants or chemicals.
While waiting for the veterinary appointment, you should try to make feeding the cat as comfortable as possible. Soft food that is easy to chew and swallow can help avoid pain when eating and encourage the cat’s appetite.
It is important to observe the cat’s symptoms closely and report any changes or additional symptoms to the veterinarian. An accurate medical historyThe medical history is the systematic collection of a patient's medical history through questioning. It includes information about previous illnesses, treatments, allergies, and lifestyle habits. can help the veterinarian make the correct diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. and plan the best possible treatment.
Outlook on current research
Current research is investigating how purple spots in the oral mucosaMucosa, also called mucous membrane, refers to the moist lining of body cavities that are connected to the outside world, such as the mouth, nose, lungs, and gastrointestinal tract. It serves to protect and facilitate the absorption of nutrients. of cats can be better understood and interpreted as a diagnostic symptom. Researchers are focusing on identifying the exact mechanisms that lead to these mucous membrane bleeding events to develop a more precise diagnosis and better treatment options. Since these bleeds can often be signs of serious health problems, intensive work is being done to decode the connections between the spots and various underlying diseases.
Another important area of research is the development of non-invasive methods for detecting and monitoring these symptoms. The goal is to develop technologies that allow veterinarians to efficiently examine a cat’s mucosaMucosa, also called mucous membrane, refers to the moist lining of body cavities that are connected to the outside world, such as the mouth, nose, lungs, and gastrointestinal tract. It serves to protect and facilitate the absorption of nutrients. without the stressStress refers to the state of an organism reacting to external stimuli or demands. In veterinary medicine, stress can have physical or psychological effects on animals, impacting their health and well-being. of a physical intervention. This can be achieved through the use of high-resolution imaging techniques or the development of new biomarkers that can be detected in the cat’s blood or saliva.
In the field of therapeutic research, the focus is on developing treatment approaches that address both the symptoms and the underlying causes. Research into anticoagulantsAnticoagulants are medications that slow down or inhibit blood coagulation. They are used to prevent the formation of blood clots and are used in dogs and cats with certain heart conditions or coagulation disorders. and other medications that affect blood coagulationBlood coagulation is a process that helps stop Bleeding when a blood vessel is damaged. Platelets and certain proteins in the plasma form a blood clot that seals the wound. is of particular interest to prevent further bleeding and promote healing.
Another interesting research direction is the study of genetic factors that might make a cat susceptible to such bleeding phenomena. By studying genetic predispositionA predisposition is an innate inclination or susceptibility of an organism to certain diseases or conditions. In dogs and cats, there may be a genetic predisposition to certain conditions such as hip dysplasia or certain heart diseases., targeted preventive measures could be developed in the future to minimize the risk of these spots appearing.
Finally, the role of environmental factors and nutrition in relation to the development of purple spots in the oralOral means "through the mouth" and refers to the intake of food, medication, or other substances through the mouth. In veterinary medicine, many treatments are administered orally. mucosaMucosa, also called mucous membrane, refers to the moist lining of body cavities that are connected to the outside world, such as the mouth, nose, lungs, and gastrointestinal tract.
