A cat's weight can vary significantly based on its breed, age, and overall health. On average, domestic cats typically weigh between 8 to 10 pounds, but some breeds, like the Maine Coon, can weigh up to 25 pounds. Maintaining a healthy weight is crucial for a cat's well-being, as being overweight can lead to various health issues. To determine if a cat is at a healthy weight, owners can consult a veterinarian or use a body condition score chart. Regular check-ups and a balanced diet are essential for keeping a cat's weight in check, ensuring they remain active and healthy throughout their life.
