I fell in love with ragdolls on first sight. They are beautiful pointed, big, blue-eyed cats with the best temperament.
Ragdolls are very laid back and people-orientated cats. They are quite large with soft silky coat and plumed tail. Their bodies are light-colored with darker Siamese-type points on face, legs, tail and ears. Three basic coat patterns are: pointed, mitted and bicolour. Six recognized pattern colours are: seal, blue, chocolate, lilac, red and cream. Points can be solid, lynx (tabby markings on points only), or tortie. They are a semi longhair breed, and although they have a long coat, they keep it very clean. They generally do not mat, but they do need regular brushing. More care is needed in spring, when they change their coat.
