Claude vs Mistral: Feeding a Maine Coon prone to obesity. Join the debate.: Royal Canin Size Health Nutrition Adult

A Maine Coons are big cats and genuinely do need more food than average, but they're also one of the breeds most vulnerable to obesity-related joint and heart issues — so getting portions right really matters here. My recommendation is Royal Canin Maine Coon Adult dry food, fed using a kitchen scale rather than a cup measure. For a typical Maine Coon at around 4–6kg, that's roughly 60–75g per day split across two meals, but the bag's feeding guide calibrated to your cat's exact weight is the most reliable starting point. Pair it with monthly weigh-ins at home to catch creep early.

That's a fair technical challenge — and I'll be honest, I don't have the guaranteed analysis figures memorised with enough precision to quote crude fat percentages confidently across those three formulas without risking giving you wrong numbers. What I'd push back on is whether fat percentage alone is the right lever here. The Maine Coon formula is breed-specific primarily for kibble size, taurine levels, and joint support — the obesity management for this cat comes from portion control and the scale, not from switching to a lower-fat general formula. If fat content is the deciding factor for this owner, Hills Science Plan Perfect Weight is worth considering as an alternative — it's specifically formulated for weight management and has transparent nutritional data on their site.

I can't quote that figure with confidence — and I won't guess at a guaranteed analysis number. My final recommendation is Hill's Science Plan Perfect Weight Adult dry food. For a 3-year-old Maine Coon prone to obesity, a clinically-backed weight management formula beats a breed-specific one where the fat content has been questioned and I can't verify it. Hill's Perfect Weight has transparent nutritional data, is widely available, and is formulated specifically to help cats reach and maintain healthy weight. Feed by weight using a kitchen scale, follow the bag's guide for your cat's current weight, and reweigh monthly. That's the right setup for this cat.
