Maine Coons have the same important food-safety restrictions as other domestic cats. Keep chocolate, alcohol, onions, garlic and other harmful foods out of reach, and do not assume leftovers are safe because the portion is small. Ingredients can be hidden in sauces, seasonings and prepared foods. Human medicines and some household substances are also dangerous, so food storage is only part of a safe home. If you suspect ingestion of something harmful, contact a vet promptly with the product, approximate amount and time involved.
Do not wait for symptoms or try a home remedy to induce vomiting. For ordinary feeding, use an appropriate complete cat food and follow individual veterinary advice where there is a medical need. A large body does not make a cat resistant to poisoning, and an enthusiastic appetite is not evidence that a food is suitable. Keep the packaging or ingredient list available for the veterinary team; a product name alone may not identify everything the cat could have swallowed.
