Panosteitis in Cats: Vet Guide 🐱🦴 2025
By Dr Duncan Houston BVSc, veterinarian & founder of Ask A Vet.
Panosteitis, often called “growing pains,” is a painful, self-limiting inflammation of the long bones—most often seen in young, medium- to large-breed cats aged 5–18 months. Though rare compared to dogs, it's important to recognize and treat it promptly to ease your kitten’s discomfort and support full recovery. 🚶♂️
🔍 What Is Panosteitis?
Panosteitis is bone inflammation affecting the medullary cavity and shaft, causing intermittent lameness that "shifts" from leg to leg. Radiographically, it’s marked by:
- Decreased opacity near nutrient foramina
- Increased medullary opacity and fuzzy endosteal/periosteal new bone
These changes often lag behind clinical signs by days or weeks.
⚠️ Who Is Affected?
- Typically kittens aged 5–18 months; sometimes as young as 2 months
- More common in medium-to-large breeds, male cats slightly overrepresented
- Episodes may recur until around 2 years old and then resolve
🚨 Clinical Signs
Watch for:
- Sudden lameness in a limb, shifting from one to another
- Pain on palpation of long bone shafts
- Sometimes accompanied by fever, anorexia, lethargy, muscle wasting
🧪 Diagnosis
- Physical exam and palpation to localize pain
- Radiographs—may lag; repeat imaging can confirm diagnosis
- Rule out other causes (fracture, osteomyelitis, arthritis)
- Occasionally nuclear scintigraphy detects early changes
🛠️ Treatment & Management
Treatment focuses on pain control and gentle activity restriction:
- NSAIDs (e.g., meloxicam) to relieve inflammation and fever
- Other pain relievers like tramadol or gabapentin if needed
- Short-term cage rest during flare-ups; normal light play in between episodes
- Encourage appetite and hydration; consider palatable wet food or supplements
- Some anecdotal use of omega-3s, antioxidants, or CBD—but vet-prescribed standard therapy is preferred
📆 Prognosis & Follow-Up
- Symptoms typically last 2–5 weeks per episode
- Recurrence until ~2 years; after that complete resolution is expected
- Radiographic abnormalities resolve as bone normalizes
- If lameness persists past 4–5 weeks, reassess for other orthopedic diseases
🏠 At-Home Care Tips
- Monitor gait and comfort daily
- Keep activity mellow during flare-ups
- Ensure a comfortable padded resting area
- Offer easily digestible, nutritious meals
- Track episodes and response to treatment
- Follow-up exams every 2–4 weeks until lameness resolves
