Delayed Blood Clotting in cats
“Delayed blood clotting” in cats refers to the extended time it takes for blood to clot and stop bleeding after an injury. This can lead to persistent or excessive blood loss and is indicative of an underlying disorder in the cat’s coagulation system.
Can Occur with the Following Diseases:
- Acute Liver Insufficiency (Acute Liver Failure)
- Disseminated Intravascular Coagulation, DIC (Impaired Blood Clotting in Shock)
- Hepatically Induced Coagulopathy (Liver-Related Blood Clotting Disorder)
- Coagulopathy Due to Clotting Factor Deficiency (Clotting Factor Deficiency, Genetic)
- Thrombocytopathies (Blood Clotting Disorders Due to Platelet Dysfunction)
- Cyclic Neutropenia (Chediak-Higashi Syndrome)
- Thrombocytopenia (Low Platelet Count)
Basics and possible causes
Blood clotting is a complex process that requires a number of factors, including platelets (thrombocytes) and coagulation proteins produced in the liver. In the event of an injury, a signal is triggered that activates the platelets to attach to the injured site and form an initial seal. Coagulation factors are then activated, triggering a cascade of reactions that ultimately lead to the formation of a stable fibrin clot.
Delayed blood clotting can be caused by a variety of factors. A common reason is a deficiency of platelets, either due to their increased breakdown or insufficient production in the bone marrow. Conditions such as thrombocytopenia are responsible for this.
Liver diseases are also a common cause of coagulation disorders, as the liver is responsible for producing most coagulation factors. Impaired liver function can lead to an insufficient amount of coagulation proteins in the blood.
Poisoning, especially from certain rodenticides (rat poisons) containing anticoagulants, can also impair the blood’s ability to clot. These poisons work by preventing the reprocessing of vitamin K, an essential nutrient for the synthesis of several coagulation factors.
Inherited coagulation disorders, such as hemophilia, can also delay blood clotting. However, these genetic conditions are relatively rare in cats compared to other species.
Typical accompanying symptoms
-
Increased Bleeding: Cats with delayed blood clotting may bleed longer after minor injuries or have spontaneous Bleeding, such as nosebleeds or Bleeding gums.
-
Bruising: Unusually large or frequent hematomas (bruises) may occur with minimal trauma.
-
Anemia: Due to chronic Blood loss, cats may appear pale, lethargic, and exhibit an increased respiratory rate.
-
Blood in urine or stool: Hematuria (Blood in urine) or melena (dark, tarry stool) may indicate internal Bleeding.
-
Swelling: Swelling or Pain may occur upon touching due to Blood accumulation in the tissue.
When to visit the vet?
A visit to the vet is urgently needed if a cat shows signs of excessive or persistent Bleeding, even after minor injuries. This is especially critical if the Bleeding does not stop or the cat shows signs of weakness and lethargy.
If the cat shows symptoms such as repeated nosebleeds, Blood in the urine or stool, or unusual bruising, veterinary advice should be sought immediately. These symptoms may indicate serious internal Bleeding that can be life-threatening.
If poisoning is suspected, especially if the cat has had access to rodenticides or other known toxins, an immediate veterinary visit is essential to take countermeasures and prevent further damage.
Symptom recognition for animal owners and veterinary diagnostic procedures
The detection of delayed blood clotting by the pet owner can be a challenge, as the symptoms can be subtle. Regular checking of the oral cavity, nasal openings, and skin for Bleeding or bruising can help to identify early signs.
The veterinarian will perform a thorough history and physical examination to narrow down possible causes. Blood tests are crucial and usually include a complete blood count to determine the platelet count, as well as special coagulation tests such as prothrombin time (PT) and activated partial thromboplastin time (aPTT).
If liver disease is suspected, liver enzymes and other specific tests will be performed to assess liver function. If poisoning is suspected, the veterinarian may order specific tests or begin treatment based on clinical symptoms.
What can pet owners do and professional therapy options
As a pet owner, it is important to keep the cat calm to avoid further injury. Stress and excessive exercise can increase Bleeding. Make sure the cat stays in a safe environment until it can be taken to the vet.
In the case of external Bleeding, gentle pressure on the wound can help slow the Bleeding until professional help arrives. However, it is important not to manipulate the cat too much to avoid undue Pain or stress.
Do not give the cat any medication that is administered without veterinary advice, as some medications can further impair blood clotting. The veterinarian will determine the best treatment strategy based on the diagnosis and underlying cause.
If poisoning is suspected, try to gather as much information as possible about the potential poison, including the packaging or description of the product, to provide targeted information to the veterinarian. This can be crucial for the rapid and effective treatment of the cat.
