Tips and FAQs

My animal is very old/sick and has not been vaccinated against rabies; does he still need to be vaccinated?

Yes, unless otherwise instructed by your vet. If so, you will need to provide a letter from the veterinarian stating that they will not vaccinate your pet for medical reasons.

Does my cat need to be licensed?

No cats are not required to be licensed, though the Animal Commission recommends that they wear a safety collar and Id Tag. Please note as stated above that they should be vaccinated for rabies, even if kept indoors.

Does my cat need to be vaccinated for rabies?
