Cat Obesity: Essential Vet Guide for 2025 🐱⚖️

Hello! I’m Dr Duncan Houston BVSc, feline veterinarian and founder of Ask A Vet. In 2025, **obesity** has become one of the most common nutritional disorders in cats—even surpassing some infectious or chronic diseases. This guide dives deep into what obesity really means for your cat, how to identify it, why it’s dangerous, and how safe weight loss can restore health and vitality. We'll also explore how **Ask A Vet**, **Woopf**, and **Purrz** can support your journey. 💙

📌 What Is Cat Obesity?

Obesity is defined when a cat’s body weight exceeds its ideal by more than 20%, while being 10–20% over ideal weight is considered overweight :contentReference[oaicite:3]{index=3}. In developed countries, up to 60% of cats are overweight or obese :contentReference[oaicite:4]{index=4}.

⚠️ Why It Matters

• Health risks: Obesity triples the risk of diabetes mellitus and increases risks for arthritis, urinary disease, hypertension, respiratory issues, certain cancers, and fatty liver disease (hepatic lipidosis) :contentReference[oaicite:5]{index=5}.
• Reduced lifespan & vitality: Obese cats live shorter, less active lives :contentReference[oaicite:6]{index=6}.
• Misleading appearance: Around 28% of owners think their overweight cat is a healthy weight :contentReference[oaicite:7]{index=7}.

🌐 Who Is Affected?

• Middle-aged and senior cats are most at risk :contentReference[oaicite:8]{index=8}.
• Indoor cats, sedentary lifestyles, and free-feeding habits are common factors :contentReference[oaicite:9]{index=9}.
• Neutered cats have increased metabolic risk :contentReference[oaicite:10]{index=10}.

🔍 Spotting the Signs

Use a body condition score (BCS) chart—ideal score is 4–5/9; 6–7 indicates overweight; 8–9 shows obesity :contentReference[oaicite:11]{index=11}.

• Look for a rounded shape from above with no waist, a sagging abdomen, and inability to feel ribs under light pressure.
• Move more slowly and avoid jumping or playing.

🔬 Medical Complications

• Diabetes: Fat cells disrupt insulin sensitivity—obese cats are 3× more likely affected :contentReference[oaicite:12]{index=12}.
• Arthritis & pain: Up to 20% of lameness cases could be prevented with weight loss in cats :contentReference[oaicite:13]{index=13}.
• Hepatic lipidosis: At risk if anorexic; obesity is a known trigger :contentReference[oaicite:14]{index=14}.
• Other risks: urinary disease, hypertension, respiratory strain, cancer, inflammation, endocrine imbalances :contentReference[oaicite:15]{index=15}.

🛠️ Veterinary Weight Loss Protocol

1. Vet check-up first: Rule out health issues and establish target weight and calories :contentReference[oaicite:16]{index=16}.
2. Calculate Daily Energy Requirement (DER): Use formula based on target weight. Typical goal: lose ~0.25–0.5 kg/month :contentReference[oaicite:17]{index=17}.
3. Select food: Use therapeutic weight-loss diet—high protein, low carb, moderate fiber; avoid simply reducing maintenance food :contentReference[oaicite:18]{index=18}.
4. Feed precisely: Weigh meals, avoid free feeding, use puzzle feeders, limit treats, increase activity :contentReference[oaicite:19]{index=19}.
5. Monitor & adjust: Monthly weigh-ins, adjust calories if weight loss stalls :contentReference[oaicite:20]{index=20}.
