My ex wife, me and my son had a cat together in Denmark. Now they have to move to a place in Denmark where they cannot have pets. Since my daughter has just died, it is vital for my son that I take care of the cat, that I bring it to my house in Costa Rica. I would love to do that. Question is, can my sister bring it from Denmark? I am already in Costa Rica, but she will come visit anyway, I just wonder whether it HAS to be me travelling with the cat, the actual importer? If my sister brings it, will we have to do different, and more complicated paperwork - I know of a rabies vaccine (at least 1 month old) and vaccines for feline viral rhinotracheitis, calicivirus and panleukopenia, and a no more than 10 days old certificate. Is a chip mandatory (my cat has an idea tattooed in the ear)? Anything else?
