Who is fatter, a cat or a cat? - briefly
A cat cannot be fatter than another cat unless their physical conditions differ, as they are the same species.
Who is fatter, a cat or a cat? - in detail
When comparing the weight of one cat to another, the answer depends entirely on the specific cats in question. Cats, as a species, exhibit significant variation in size, weight, and body composition due to factors such as breed, age, diet, activity level, and overall health. For example, a Maine Coon, which is one of the largest domestic cat breeds, can weigh up to 25 pounds or more, while a Siamese cat typically weighs between 8 to 12 pounds. Similarly, individual cats within the same breed can differ in weight based on their lifestyle—indoor cats may be more prone to obesity due to reduced physical activity, whereas outdoor cats often maintain a leaner physique. Additionally, age plays a role; older cats may gain weight due to a slower metabolism, while younger, more active cats tend to be slimmer. Therefore, determining which cat is "fatter" requires analyzing the specific characteristics and circumstances of each cat. Without such details, it is impossible to make a definitive comparison.
