My understanding is QAWS ask that you pay the veterinarian costs (vaccinations, neutering, any other medical) that have been paid by QAWS.

As these are the same costs you would have to pay as a loving pet owner anyways PLUS you would have to take the animal to and from the vet office, this is very fair.

Also, in this way you know the animal you are adopting is healthy - unlike an animal bought from the pet trade.
