I had to be checked by a vet before I could go back to London. We went to Park East Animal Hospital so they can stamp my passport.
In addition I also got a rabies tag which was essential in the U.S. It basically tagged me as rabies free – just in case I got lost and if I didn’t have that, they could throw me into quarantine and all sorts of horrible things!
I passed all tests with flying colours. And my passport got stamped!
