Which registries describe this breed?
Registries such as CFA in the United States, GCCF in the United Kingdom, and ACF in Australia publish a conformation description for many pedigreed cats. That description covers coat, size, and typical temperament. It does not diagnose heart disease, urinary blockage, or any other illness in the cat you live with.
Daily calorie and portion estimation
A typical adult Maine Coon starts near 380 kcal/day, with about 20 minutes of steady daily activity. Enter the current weight in pounds (kilograms) in the calculator, because a lean animal and an overweight animal do not share the same portion.
Large does not mean unlimited food. Feed to a waist you can see from above, and brush the belly and britches so mats do not form. Measure meals in ounces (grams), and keep treats near ten percent of the daily calorie target.

What should Maine Coon owners ask first?
Owners most often ask about housing, grooming, and which signs cannot wait. The answers below are educational ranges for a typical Maine Coon, including weight in pounds (kilograms) and yearly costs in dollars and pounds. They do not diagnose the animal you live with.
How big should a Maine Coon be?
Many adults land between about 10 and 20 pounds, with males often heavier. A veterinarian should confirm the cat is muscular rather than overweight. These points are educational ranges, and a veterinarian who has examined your animal still has to confirm them.
What heart sign cannot wait?
Open-mouth breathing at rest, or sudden inability to use the hind legs, is an emergency. Maine Coons are predisposed to hypertrophic cardiomyopathy. These points are educational ranges, and a veterinarian who has examined your animal still has to confirm them.
