Although curl varies by hair length, sex and age in an individual, the entire coat should show the effect of the rex gene. Curliness may be evident more around the neck, on the tail and the belly. Allowance should be made for less curl on younger adults and kittens. The longhair Selkirk Rex should have plumy tail hairs standing away from the tail. All body colors and color patterns that are genetically possible in the cat may occur in the Selkirk Rex.
Color is secondary in importance to other factors.
Extreme nose break, lack of visible muzzle, malocclusion, tail kinks, crossed eyes, obvious physical deformities, including polydacty feet, no evidence of curl.
