you want to purchase a kitten you have to know exactly
what you're looking for. Is it going to be a family companion
or a cat you intend to breed in future. If you are looking
for a family pet, then you need to find a kitten that
is realatively compatible with you and your family. Avoid
pet shops. Animals in them look cute but often lack shots
and are often get sick.
When you pick your kitten, you should consider the type
of home it comes from and it's mother's state of health.
Do not buy a kitten from a breeder that will not let you
see the mother cat. You don't want the mother to be sick.
If a cat is pedigree that does not mean the cat is a good
one. Pedigree cats are often inbred and are prone to disease.
