Coat varieties

All colours and markings are allowed in both coat varieties.

1 ) SMOOTH aka NORMAL (sk)

Coat to be smooth, thick, soft and naturally shiny. It should have longer top fur and softer base fur.

2) REX aka CURLY-HAIRED (rex) 

Coat to be even, thick and not too coarse. As few guard hairs as possible. Coat to be evenly curly all over. A less curly belly side allowed. Whiskers to be curly as well. When a silver-ticked or ticked (agouti-group varieties) rat is rex, less ticking is allowed because there are less guard hairs in their fur than in smooth rats. Rexing may have a balding effect in elderly rats, which is normal and should not be punished in judgement. Hand stripping (trimming) the coarse guard hairs before showing a rex rat is optional. Stripping should not cause the rat any pain.
