To travel into the Cayman Islands, all pets must be permanently identified with a microchip or tattoo.
After this your pet must be vaccinated with a rabies vaccine. Your pet must be at least 12 weeks old when this is done. It is recommended that your pet receive a booster vaccine 30 days later, before the blood test.
The blood test should be done at least 2 weeks after the rabies booster. It is done to check for protective antibodies against rabies and must be carried out by a lab that is approved by the Cayman Islands government.
Six month after the blood results from the titer are back, and provided it has passed the test (which they do in the vast majority of cases), your pet is almost ready to travel.
Within 14 days of your scheduled date of travel, your pet must get a health certificate from a licensed veterinarian. Your pet must be treated for tick and tapeworms and must be up-to-date on all vaccinations. The certificate must also be endorsed by a full time government veterinarian of the county of origin (e.g. USDA, Canadian Food Inspection Agency, Defra in the UK).
Once in the Cayman Islands, all vaccinations and blood tests must be kept up-to-date as recommended by the Cayman Islands Department of Agriculture.
There are certain prohibitions on breeds of dogs allowed so you must be sure to check this out before coming.
