LaPerm kittens are born hairless or with a short, wavy or straight coat. They will go through a balding period where all their hair falls out at about two weeks. Their new coat then comes in and they remain in varying stages of baldness until the full coat comes in at four months. If they were born with a curly coat they will retain a curly coat. It should be soft, and should have a shaggy appearance. This breed comes in two coat lengths, long and short. The long haired version should have a ruff on the neck at maturity and be free of matting. The tail should be plumed with some curling. It should also be loose and bouncy so that you are able to run your fingers down to the skin. The short haired coat should be springy, light and airy. The tail is not plumed but may be wavy.
The head of the breed is a modified wedge, slightly rounded with gentle contours. The muzzle is broad and ends in a strong chin. Ears should be set so they continue the wedge of the head, slightly flared and medium to large in size. Full furnishings and earmuffs with lynx tipping are preferred in the long haired coats. Eyes are medium-large and expressive. They should be almond shaped when resting and round when alert. They can be any color that naturally occurs.
The body is moderate in size with medium to fine boning. Legs should be medium long and match the body, ending in rounded feet.
