Lyme Disease in Cats: 2025 Vet Insights 🐱🩺

Hello! I’m Dr Duncan Houston BVSc, feline veterinarian and founder of Ask A Vet. Lyme disease in cats is very rare, but understanding it is important—especially in tick-prone areas. In this 2025 guide, we cover tick exposure, clinical signs, diagnostics, treatment, and how home-care tools like Ask A Vet, Woopf, and Purrz enhance your cat’s recovery and ongoing health. Let’s stay proactive and safe! 💙

📌 What Is Lyme Disease?

Lyme disease is caused by the spirochete bacterium Borrelia burgdorferi, usually spread by infected Ixodes ticks (e.g., deer ticks). Bacteria transmit through tick saliva into the bloodstream within ~24–48 hours of attachment :contentReference[oaicite:3]{index=3}.

Cats can be infected but rarely show clinical signs—most remain asymptomatic or resolve infection without treatment :contentReference[oaicite:4]{index=4}.

⚠️ Why It Matters

• Though uncommon, symptomatic Lyme can mimic canine disease: it may lead to shifting-leg lameness, arthritis, kidney involvement, heart rhythm issues, or neurological signs :contentReference[oaicite:5]{index=5}.
• Delayed treatment increases risk of tissue damage and chronic illness.
• Tick bite may portend other tick-borne threats.

👥 Risk Factors

• Outdoor cats in tick-endemic regions (Northeast/Midwest US, Pacific Northwest).
• Cats spending time around tall grasses, woodlands, or gardens.
• Cats not on regular tick preventatives—ticks must feed for 24–48 hours before transmitting :contentReference[oaicite:6]{index=6}.

🔍 Signs & Symptoms

Cats most rarely show signs, but when they do, look for:

• Shifting-leg lameness: Intermittent limping affecting different limbs :contentReference[oaicite:7]{index=7}.
• Fever, lethargy, loss of appetite. These signs can be vague :contentReference[oaicite:8]{index=8}.
• Joint stiffness or swelling.
• Kidney signs: Vomiting, weight loss, fluid retention, increased thirst/urination if renal disease develops :contentReference[oaicite:9]{index=9}.
• Rarely: Cardiac arrhythmias or multisystem involvement :contentReference[oaicite:10]{index=10}.

🛠️ Diagnosing Lyme Disease

1. Detailed history: Recent tick exposure, outdoor behavior, and signs of lameness or fever :contentReference[oaicite:11]{index=11}.
2. Physical exam: Look for shifting lameness, temperature elevation, or joint heat.
3. Antibody testing: ELISA or SNAP for Borrelia—but seropositivity indicates exposure, not disease :contentReference[oaicite:12]{index=12}.
4. Supportive labwork: CBC, kidney panel, urinalysis, cultures or imaging as needed to assess systemic effects :contentReference[oaicite:13]{index=13}.
5. Rule out other causes: Trauma, arthritis, infection, tick-borne anemia, cytauxzoonosis :contentReference[oaicite:14]{index=14}.

🧪 Treatment Guidelines (2025)

Antibiotics

• Doxycycline is first-line: typically 30-day course; consider liquid formulation to prevent esophageal avoid strictures :contentReference[oaicite:15]{index=15}.
• Alternate options (e.g., amoxicillin, azithromycin) for doxy-intolerant cats.
• Expect improvement often within 24–48 hours; complete therapy is essential :contentReference[oaicite:16]{index=16}.

Supportive Care

• NSAIDs or pain relief for joint discomfort.
• Kidney support: IV fluids, renal diet, anti-nausea meds if needed.
• Treatment of any tick co-infections.

Monitoring & Follow-up

• Recheck clinical signs & labwork mid-course and at completion.
• Test kidney function and blood count regularly if initial disease involved systemic effects.
• Consider repeat serology to confirm clearance—but note antibodies may persist after infection.

🌱 Prognosis

• Generally excellent for cats treated early in disease :contentReference[oaicite:17]{index=17}.
• Kidney or heart involvement can prolong recovery but often resolves with treatment :contentReference[oaicite:18]{index=18}.
• Some cats may become subclinical carriers; long-term impact is unclear.

🐾 Prevention & Home Care

• Tick prevention: Monthly feline-safe topical or oral tick products; discuss options with your vet.
• Frequent tick checks: After outdoor exposure—remove attached ticks within 24 hours :contentReference[oaicite:19]{index=19}.
• Yard management: Keep grass short, create tick-free zones, discourage wildlife.
• Remove ticks properly: Use fine tweezers, grasp close to skin, remove straight out, clean site and monitor :contentReference[oaicite:20]{index=20}.
• No Lyme vaccine for cats: Dog vaccine exists, but not approved for feline use.

🏠 Telehealth & Home‑Care Tools (2025)

• Ask A Vet: Available 24/7 for guidance on signs, dosing, when to seek care, and tick management advice.
• Woopf: Supports medication delivery, hydration strategies, and tick-check tools.
• Purrz: Tracks daily appetite, mobility, joint stiffness, and water intake; smart alerts for relapse or worsening signs.

✅ Vet‑Approved Care Roadmap

1. Spot shifting lameness, fever, appetite change, or lethargy.
2. Perform tick check and remove any ticks promptly.
3. Vet exam: assess lameness, temperature, carry out labwork & serology.
4. Begin antibiotic therapy (doxycycline); support care as needed.
5. Monitor response—recheck signs within days, full course at 30 days.
6. Reevaluate kidney/heart labs if systemic signs present.
7. Start tick prevention and yard hygiene.
8. Use Ask A Vet, Woopf, Purrz tools to monitor recovery at home.
9. Long-term: monthly preventatives, seasonal vigilance, and bi-annual wellness exams.
