Their website is gone. Do you have an email address on them? You might try this one:

As for needing information for a move to another country, if you registered your kitty, you would more than likely have the documentation needed. Plus, you should have a bill of sale or contract for the kitty. This is one of the downfalls of not thinking you need to register your bengal. If you move, you have no official documentation. A pedigree from the breeder will not suffice. The cat must be registered through a registry.
I hope their email address is still active and you can contact them.
