For the import regulations, see the BVet website:

(I see they have a new format - enter the reason for bringing your pet, what kind of animal, how many, and the country you come from - and hey presto, all the info you need to know.)

As for prices, this will vary - ask your airline or pet shipper for a quote.

There have been many threads discussing the importation of pets into switzerland - do a quick search to read up on other poster's experiences.

Good luck with your trip, and hope your kitty enjoys his/her Swiss adventure.
