* Breed: Some breeds, like Maine Coons, are significantly larger than others, like Siamese cats.
* Age: Kittens are smaller than adult cats.
* Individual variation: Even within a breed, cats can vary in size and build.
* Whether the cat is lying down or standing: A cat lying down will obviously have a different width than a cat standing up.
However, here's a general idea:
* Average adult cat width (chest): About 6-12 inches (15-30 cm)
* Average adult cat width (hips): Similar to chest width
* Kittens: Much smaller, obviously, but this will vary significantly by age.
To get a more accurate idea of your cat's width, measure their chest or hips using a tape measure.
