Keeping Your Persian at a Healthy Weight
-
Measure meals
Persians need 150–280 kcal/day. Free-feeding dry kibble is the most common cause of feline obesity.
-
Daily play sessions
15 minutes of interactive play daily helps maintain muscle tone and a healthy weight.
-
No treats from the table
Human food is often too calorie-dense and can contain toxins. Use cat-specific low-calorie treats.
-
Encourage water intake
Well-hydrated cats tend to eat less and have better kidney health. Try a water fountain.
-
Annual vet weigh-ins
Cats can gain weight gradually — a vet visit ensures subtle changes are caught early.
