If you are talking about a breeder in the states shipping to Germany, you are limited. There are not too many of any cat breeders that are willing to ship overseas - mostly because of all the paperwork, time, regulations, etc. that are involved.
I did post two German breeders for you to check out in your other thread in the Breeder's section
If you get them in Germany, it would be less hassle bringing them back to the states (still will have about 1/2 ton of paperwork rather then a ton
Most breeders that ship have long standing connections with another breeder in the other country and not just a person wanting one of their kittens.
