Crit modifier for bite / claws

[GoldEdition42]

I can't seem to find what the threat range/crit modifier for my tiger's bite/claws.

Do they have any?

20 x2

Edit: Gave answer befor proof to avoid Ninja's.

critical hits section of combat chapter in CRB wrote:

A critical hit means that you roll your damage more than once, with all your usual bonuses, and add the rolls together. Unless otherwise specified, the threat range for a critical hit on an attack roll is 20, and the multiplier is ×2.

If it doesn't specify otherwise, attacks are x2 threatens a crit on a 20.

I was pretty sure that would be the default answer. Good to know.
