Helping your cat lose or gain weight

 

Maintaining an ideal weight is vital for your cat’s longevity. Whether your new rescue needs to put on muscle or your "indoor hunter" needs to shed a few pounds, a gradual approach is the safest way to see results.

Identifying the Goal

Before changing any diet, use the Body Condition Score (BCS).

• Underweight: Ribs and spine are prominent with no palpable fat.

• Ideal: You can feel the ribs easily, and there is a visible waistline when viewed from above.

• Overweight: The waistline is absent, and there is a noticeable "fat pad" on the abdomen.

Safe Weight Loss Strategies

Rapid weight loss in cats can lead to Hepatic Lipidosis (fatty liver disease), which is life-threatening. Aim for a loss of only 1% to 2% of body weight per week.

• Eliminate Free-Feeding: Switch from an open kibble bowl to 2–4 scheduled meals.

• Prioritize Wet Food: High-protein, low-carb canned food is more satiating and less calorically dense than dry kibble.

• Active Feeding: Use food puzzles or "hide" kibble around the house to encourage movement.

Healthy Weight Gain Strategies

For cats that are underweight due to age or stress, focus on calorie density and palatability.

• Kitten Food: Feeding a high-quality kitten formula provides extra protein and fat for adult cats needing a boost.

• Small, Frequent Meals: Offer 5–6 small portions a day to avoid digestive upset.

• Aroma Boost: Warm wet food to approximately 38°C (100°F) to release scents that stimulate a finicky appetite.

Monitoring Success

Check your cat’s weight weekly. If there is no change after 3 weeks, adjust their daily caloric intake by 10%. Always consult your veterinarian if your cat refuses to eat for more than 24 hours or exhibits sudden lethargy.
