A cat or kitten described as a pure-blood is an animal with its registration.
A breed in development must have its registration and its code.
When you pay your animal, at the same time, make certain to see the litter registration, fill it with the breeder and ask for a copy or you would risk to never get it.
The kitten must have been wormed and vaccinated. Ask for his health bulletin from the veterinarian. Ask the booster date for the worming and the vaccination. In Canada, only a veterinarian has the right to vaccinate.
You must have health guaranties when you buy a kitten and read them before signing. If the breeder do not want to give you guaranties, do not take the animal.
Ask for your invoice.
Never take possession of a kitten before it is 4 months old. A kitten develop slowly and the change of surroundings can bring it health problems, due to the stress of adapting, if it is too young.
If a kitten has to be ship by air, it must not happen before 4 months old and even older depending of the breed.
Ask for a bag of the food it's already eating, so the kitten doesn't develop a diarrhoea. If you intend to use a different dry food, mix your to his on a period of at least 10 days. Any rapid change is not advice.
Anybody can put a cat and a queen together and produce kittens. But it's not just any breeder that can produce kittens of quality, in good health, with a good conformation, a good temperament and give you solid health guaranties and your registration.
The buying of an animal must always be done with much seriousness.
