🐶🐱 Cleft Palate or Lip in Puppies and Kittens: A 2025 Vet Guide to Diagnosis and Care 🍼

By Dr Duncan Houston, BVSc

Birth defects of the mouth, such as cleft palate or cleft lip, are not uncommon in puppies and kittens. These conditions affect the structures that normally separate the mouth from the nose. When they don’t form correctly, feeding becomes difficult or dangerous — and urgent care is needed. 🩺

🧬 What Is a Cleft Palate or Lip?

• 💋 Cleft Lip: A visible gap or misshaping in the lip, sometimes connecting the nostrils to the mouth
• 🧠 Cleft Palate: A hole or disconnection in the roof of the mouth, which can be in the hard or soft palate

These defects develop in the womb and can vary in severity. In the worst cases, there’s an open connection between the mouth and nasal passages, which makes normal feeding impossible. 🍼

❗ Why Are Cleft Defects a Problem?

• 🐾 Newborns may struggle to latch and suckle milk
• 🥛 Milk may leak into the nose → leading to infection or pneumonia
• 📉 Affected pets often show poor growth and energy

Without assistance, puppies and kittens with significant clefts may fail to thrive. 🚨

⚠️ What Causes Cleft Defects?

🧬 Inherited Conditions:

Genetics play a major role. Pets born with cleft palates or lips should not be bred, as the condition is likely to be passed on. 🚫

🔬 Other Potential Causes:

• 💊 Medications during pregnancy (e.g., steroids, aspirin, seizure meds, griseofulvin)
• 📉 Folic acid deficiency or excess vitamin A
• 🦠 Viral infections in the pregnant mother
• 🤕 Trauma during fetal development

Thankfully, most of these are rare in pets with good prenatal care. 🧼

🔍 How to Recognize the Signs

🐶 Obvious Signs:

• 💋 Visible facial defect or “harelip”
• 🍼 Trouble suckling or feeding
• 💧 Milk leaking from the nose
• 💨 Nasal discharge, especially green or cloudy

🧪 Subtle or Delayed Signs:

• 📉 Poor weight gain or development
• 💤 Lethargy or reduced activity
• 🫁 Coughing, gagging, or pneumonia from aspiration

🩺 Diagnosis and Imaging

A veterinarian will perform a physical exam to check for visible clefts. Sedation may be used to inspect deep inside the mouth. If respiratory symptoms are present, your vet may recommend:

• 🩻 Chest X-rays to check for pneumonia
• 🧪 Bloodwork to assess infection or illness
• 🧠 CT or MRI (rare) if surgery is planned or if other defects are suspected

💉 Treatment Options

✅ Mild Cleft Lip (No Nasal Opening):

• May require no treatment if it doesn’t affect eating or cause infections

🛠️ Moderate to Severe Cleft Palate:

• 🥄 Tube feeding needed until pet is strong enough for surgery
• 🩺 Surgery often delayed until 3–6 months of age if possible
• ⚠️ Multiple surgeries may be required for full repair

🫁 If Pneumonia Develops:

• 🏥 Hospital care with IV fluids
• 💊 Antibiotics and oxygen support

💸 What About Surgery Costs?

Surgery can be expensive and complex, especially if done in stages. Discuss all options and get an estimate from your vet or a veterinary surgeon. 🧾

📈 What’s the Prognosis?

💚 Good: Mild clefts with no nasal opening, no feeding issues, no pneumonia
🟡 Guarded: Severe clefts with feeding difficulty or pneumonia
🔴 Poor: Severely ill or underweight puppies/kittens with uncorrectable defects

🐾 With early intervention and surgical care, many cleft-affected pets can grow up to live normal lives. But success depends heavily on nutrition, infection control, and appropriate timing of surgery.
