Moderate severity
Feline Obesity
Over 50% of pet cats are overweight. Leads to diabetes, arthritis, and heart disease.
⚠️ Common symptoms
Feline obesity has reached epidemic proportions — surveys consistently find that 50–60% of pet cats are overweight or obese. Despite being one of the most preventable health conditions, it remains vastly underdiagnosed, partly because owners normalise the "chubby cat" appearance and partly because asking about pet weight is still an uncomfortable conversation.
Obesity accelerates virtually every major feline disease. It doubles the risk of diabetes, significantly worsens osteoarthritis, increases cardiovascular strain, elevates blood pressure, impairs immune function, and increases anaesthetic and surgical risk. Obese cats have significantly shorter lifespans — studies in dogs (where the data is more robust) suggest 10–15% shorter lives, and similar effects are expected in cats.
Neutering reduces resting metabolic rate by 20–30% and simultaneously increases appetite. Without dietary adjustment after neutering, weight gain is almost inevitable. Many owners maintain pre-neutering food quantities without realising their cat's caloric needs have dropped substantially.
Safe weight loss in cats requires slow, steady progress — targeting 0.5–2% body weight loss per week. Losing weight too quickly (more than 10–15% body weight per month) causes hepatic lipidosis, a potentially fatal condition where fat floods the liver as the body catabolises fat reserves. This is why crash diets and food withdrawal are dangerous in cats.
A combination of increased protein (to preserve muscle mass during weight loss), calorie restriction, and environmental enrichment produces the best results. Puzzle feeders, wand toys, and hunting-style feeding stations increase activity and reduce stress-related eating.
🔍 Causes
The root cause is energy intake exceeding energy expenditure — but indoor lifestyle, free-feeding of calorie-dense dry food, neutering (which reduces metabolic rate by ~20%), and lack of environmental enrichment all conspire to make obesity almost inevitable without active management. Some cats are also genetically predisposed.
🛡 Prevention
Measure food portions precisely — do not free-feed. Feed a high-protein, low-carbohydrate diet (preferably wet food). Weigh your cat monthly and adjust portions as needed. Invest in interactive play for 15–20 minutes daily — this is the feline equivalent of exercise. Puzzle feeders slow eating and add cognitive stimulation.
💊 Treatment
Portion-controlled diet, puzzle feeders to slow eating, increased playtime, weight management food.
