🐱 Is My Cat Really Overweight or Obese? Vet Guide 2025 ⚖️

Hello dedicated cat parents! 😊 I’m Dr Duncan Houston BVSc. In 2025, cat obesity is a common and serious issue, affecting more than 60 % of cats. Excess weight increases the risk of diabetes, joint problems, urinary issues, and shortens lifespan. This in-depth guide will help you accurately assess your cat’s weight, understand the risks, and implement safe weight management with expert support—especially from Ask A Vet.

1️⃣ Understanding Overweight vs Obese

• A cat is considered overweight at 10–20 % above ideal body weight, and obese when over 20 % excess :contentReference[oaicite:2]{index=2}.
• Prevalence: about 61 % of cats in developed countries are overweight or obese :contentReference[oaicite:3]{index=3}.

2️⃣ Body Condition Score (BCS): The Gold Standard

• Use a 1–9 scale: ideal = 5; 6–7 = overweight; 8–9 = obese :contentReference[oaicite:4]{index=4}.
• Look and feel: from above, a cat at ideal weight shows a waist “figure-8”. Overweight cats look rectangle-shaped, and belly sags :contentReference[oaicite:5]{index=5}.
• Palpate ribs and spine—should be felt but not seen. If they’re buried in fat, your cat is over BCS 6 :contentReference[oaicite:6]{index=6}.

3️⃣ Who Is at Risk?

• Middle-aged (8–12 years) indoor cats, especially neutered ones :contentReference[oaicite:7]{index=7}.
• Poor diet—high carb dry food, free-feeding :contentReference[oaicite:8]{index=8}.
• Low activity levels due to indoor living or arthritis :contentReference[oaicite:9]{index=9}.

4️⃣ Health Risks of Excess Weight

• Increased risk of diabetes (×3), arthritis, urinary disease, kidney strain, cancer and reduced life expectancy :contentReference[oaicite:10]{index=10}.
• Obesity is now considered a low-grade inflammatory disease, raising risk for hypertension, heart and metabolic issues :contentReference[oaicite:11]{index=11}.

5️⃣ Safe Weight Loss Guidelines

• Target gradual loss: ≤1–2 % body weight/week to avoid liver lipidosis :contentReference[oaicite:12]{index=12}.
• Calculate Resting Energy Requirement (RER) and then feed 80–90 % of RER as Weight Loss Energy :contentReference[oaicite:13]{index=13}.
• Use high-protein, high-moisture diets; measure meals with a scale—not free feeding :contentReference[oaicite:14]{index=14}.

6️⃣ Diet and Feeding Tips

• Prescription weight-loss diets (Hill’s Metabolic, Royal Canin Calorie Control, Purina OM) ensure nutritional adequacy :contentReference[oaicite:15]{index=15}.
• Combine wet and dry foods—wet for satiety and moisture, dry for convenience and dental benefits :contentReference[oaicite:16]{index=16}.
• Avoid excessive treats; opt for lean protein treats and count each calorie :contentReference[oaicite:17]{index=17}.

7️⃣ Boosting Exercise & Enrichment

• Daily interactive play (two 15-min sessions) improves energy expenditure and mental health :contentReference[oaicite:18]{index=18}.
• Food puzzles, hunting feeders, and climbing structures mimic natural behavior :contentReference[oaicite:19]{index=19}.
• Support mobility with ramps and baskets for less strain in heavier cats :contentReference[oaicite:20]{index=20}.

8️⃣ Monitoring Progress

• Weigh your cat every 1–2 weeks and adjust calories if weight loss plateaus :contentReference[oaicite:21]{index=21}.
• Reassess BCS monthly via vet or app-based tools.

9️⃣ Challenges and Troubleshooting

• Plateaus: reduce calories by ~10 %, or increase activity safely.
• Health checks: rule out thyroid, arthritis, or diabetes if weight stalls.
• Watch for pulsed hunger—add low-calorie slow feeders instead of more food :contentReference[oaicite:22]{index=22}.
