Definitely take them to the vet. There may be a problem or they may be a variant of the ragdoll breed. Ragdolls are very loving but also very quiet cats with a high pain tolerance and lose limbs.

I’ve heard of those cats but I didn’t know they suited their name so well.
I don’t know anything about pure bred cats, but I think if I hit lotto I’d try to learn about them.
