Been there done that. There is no single
blanket answer as each country is different. Most, esp in Carib, could care less.
Some have strict regulations
: like Caymans and Turks & Caicos...esp rabies free countries.
Some, like Bahamas
, just take your money
for the pet application and then never look or check.
Some, like Jamaica
, dont care as long as the animals
dont go ashore.
A surprising number of officials are afraid of cats. Dont know why.
I think there are some existing threads on this subject too.
