A unique misconception is that “if it’s natural, it can’t hurt.” Cats are sensitive to formulation errors, and supplement toxicity has been reported in real-world cases, including severe metabolic derangements after ingestion of joint supplements (Bunnell, 2023). This does not mean all supplements are dangerous; it means dosing discipline, secure storage, and veterinary oversight matter—especially in a curious, food-motivated Maine Coon.
In the home, the safest pattern is boring: one product at a time, childproof storage, and no “extra” scoops on stiff days. If multiple pets share a space, prevent cross-dosing by feeding separately and picking up leftovers. Any vomiting, marked thirst changes, sudden weakness, or collapse after a new supplement is a reason to stop and call a veterinarian. Safety is part of hip dysplasia support large cats need, because their body size can hide early trouble.
