TL;DR: Finding an engorged tick on your cat is a medium-priority concern that requires removal within 24 hours to prevent disease transmission. Contact a vet immediately if your cat shows signs of fever or lethargy.
What does an engorged tick look like on my cat?
An engorged tick is a parasitic arachnid that has attached itself to your cat and has been feeding on their blood for several days. Unlike a flat, unfed tick, an engorged tick appears as a rounded, grayish, or brownish bean-like bump. On a cat's neck, they are often felt before they are seen, especially if the cat has thick fur. These parasites can expand significantly in size as they fill with blood.
Is finding an engorged tick on my cat a medical emergency?
- The urgency level for an engorged tick is medium; while usually not a life-threatening emergency, it requires prompt attention.
- Ticks can transmit serious diseases, such as Lyme disease, Anaplasmosis, or Cytauxzoonosis, and the risk of transmission increases the longer the tick stays attached.
- You should aim to have the tick removed within 24 hours.
- If your cat appears lethargic, has a fever, or is walking stiffly, contact a vet immediately.
How can a photo of the tick help my veterinarian with triage?
- A clear, well-lit photo helps the triage staff distinguish between a parasite and a skin growth, such as a mole, nipple, or skin tag.
- Attempting to pull off a skin growth with tweezers can cause significant pain and bleeding.
- A photo can help the vet identify the specific species of tick, which provides clues about the types of pathogens your cat may have been exposed to.
Clinical Context (Merck Veterinary Manual)
In cases of suspected tick paralysis in cats presenting with limb weakness and/or respiratory impairment, a thorough search for ticks is essential, especially around the head and neck. Removal of the tick is critical for treatment. Feline patients may exhibit "asthma-like" signs such as expiratory wheeze, forced abdominal expiratory effort, and exercise intolerance. Repeated tick searches should be performed during hospitalization, especially if the animal deteriorates unexpectedly or is slow to recover. Long or matted hair should be clipped, especially about the head and neck, to facilitate tick detection.
