The typical weight of a healthy domestic cat is between 7 and 10 pounds. Some cats have builds that naturally place them outside of these bounds; however, cats much heavier than 10 pounds may be overweight and unhealthy.

Cats often gain weight after they are spayed or neutered, which puts them at an elevated risk of obesity. Before cats are fixed, males typically weigh about 1.5 pounds more than females.

Different breeds of cats have different typical weights. Siamese cats tend to be smaller than the average domestic cat, with an average between 5 and 10 pounds. Meanwhile, Maine coon cats are often much larger than domestic cats, with some healthy cats weighing as much as 25 pounds.
