By Dr Duncan Houston BVSc, Founder of Ask A Vet • 2025

Ticks can transmit a range of serious diseases to cats. While feline tick‑borne infections are less common than in dogs, they still pose significant health risks. This guide covers:

• Cytauxzoonosis (Bobcat Fever)
• Lyme Disease
• Anaplasmosis
• Ehrlichiosis
• Tularemia
• Babesiosis

1. 🧫 Cytauxzoonosis (Bobcat Fever)

A severe and often fatal protozoal infection caused by Cytauxzoon felis, transmitted mainly by lone star and American dog ticks. Signs appear suddenly—high fever, lethargy, anemia, jaundice, difficulty breathing—and progress rapidly :contentReference[oaicite:4]{index=4}.

• Treatment: Atovaquone + azithromycin plus supportive care; survival rates ~60% in treated cats :contentReference[oaicite:5]{index=5}.
• Prevention: Keep cats indoors, use tick preventatives.

2. 🧬 Lyme Disease

Caused by *Borrelia burgdorferi*, transmitted by deer ticks. Cats may be asymptomatic or show lethargy, fever, joint pain, swollen lymph nodes, decreased appetite, secondary kidney issues :contentReference[oaicite:6]{index=6}.

• Treatment: Antibiotics (doxycycline), often effective if started early.
• Prevent with tick checks and licensed preventatives.

3. 🦠 Anaplasmosis

Caused by *Anaplasma phagocytophilum*, spread by black‑legged ticks. Clinical signs include fever, lethargy, poor appetite, conjunctivitis, third eyelid protrusion :contentReference[oaicite:7]{index=7}.

• Occurs less often in cats than dogs, but still a concern.
• Treatment: Doxycycline; supportive care as needed.

4. 🧫 Ehrlichiosis

Tick‑transmitted infection (e.g., *Ehrlichia* spp.) leading to fever, anemia, lethargy, weight loss, muscle pain :contentReference[oaicite:8]{index=8}.

• Rare in cats but serious when it occurs.
• Treatment: Doxycycline plus veterinary monitoring.

5. 🧬 Tularemia

Caused by *Francisella tularensis*, transmitted via tick bite or wildlife exposure. Signs include fever, lethargy, poor eating, lymph node swelling; occasionally severe systemic illness :contentReference[oaicite:9]{index=9}.

• Treatment: Antibiotic therapy (e.g., doxycycline, enrofloxacin).
• Prevention: Tick control, avoid wildlife contact.

6. 🐾 Babesiosis

Protozoal infection (e.g., *Babesia* spp.) causing hemolytic anemia, fever, dark urine, lethargy :contentReference[oaicite:10]{index=10}.

• Rare in cats, more common in dogs.
• Treatment: Antiprotozoals (e.g., imidocarb), supportive care.

⚠️ Other Tick‑Linked Conditions

• **Tick paralysis** – Sudden weakness or paralysis from neurotoxins. Reversible once tick removed.
• **Anemia & skin infections** – Due to blood loss and bite damage :contentReference[oaicite:11]{index=11}.

🧪 Recognizing Tick‑Borne Illness

Watch for these signs 1–4 weeks post‑bite:

• High fever, lethargy, loss of appetite
• Breathing difficulties, jaundice
• Joint pain, swollen lymph nodes
• Pale gums, dark urine (hemolysis)

Early detection saves lives—don’t wait to see symptoms.

🧾 Diagnostic & Treatment Overview

• Blood tests: CBC, tick panels, PCR, blood smears
• Supportive care: fluids, transfusions, fever management
• Tick preventatives: spot-ons, collars, orals
• Tick reduction in yard and on people/pets

📊 Quick Comparison Table
