If you are traveling to Germany you will need a valid passport.
Traveling to Germany with your cat
What do you need for kitty to enter Germany?
1. Your cat/kitten must be microchipped. *
2. Your cat/kitten must have a valid rabies vaccination. **
3. You must have a valid health certificate as proof of above information.
Requirements for going back home:
There is no check on the EU side of your flight back home. You only have
to fulfill your own country's requirements. For the USA this means a health
certificate, not more than 10 days old, with proof of valid rabies
vaccination (at least 30 days old, not older than 12 months, unless a 3-year
rabies vaccine was used).
* Microchip Information
The microchip should be compliant with ISO Standard 11784 or Annex A to
ISO Standard 11785. If this is not the case the person accompanying the cat
"must provide the means necessary for reading the transponder" (which means
you must bring along a compatible chip reader).
The AVID Eurochip is available in the US and is readable in Europe. I
have also read on two different US Military websites that the HomeAgain
chips are also readable in Europe, but we have not yet been able to confirm
** Rabies Vaccine Information
A rabies vaccination is considered to be valid if it is older than 30
days but not older than 12 months, unless your cat was vaccinated with a
3-year rabies vaccine.
*** Health Certificate Information

Flying with your kitty is easy!
There are 4 major airlines that will allow you to bring your cat with you
in the cabin on transatlantic flights. They are Northwest/KLM, Delta,
Lufthansa/United. All of these airlines fly into both Hannover (HAJ),
and Frankfurt Intl. Airport (FRA).
The regulations are the same as for travel within the continental US – there
may only be one pet total in first class, only 2 pets total in coach, so you
should make reservations for your cat as soon as you book your own ticket.
The cost of carrying your pet in the cabin is higher than on US domestic
flights, and usually ranges between $110 and $125 USD.
