A big problem (especially here in Germany) is the illegal trafficking of puppies and kittens. Mothers are kept under horrific conditions, forcing them to have one littler after the other. Vets have even been caught on camera creating false pet passports and fake rabies vaccination records. The kittens are shoved in a van by the hundreds to take on the journey to their oblivious owners. Many of them die due to their young age, the inappropriate transport conditions or from viral diseases. Others die after their adoption or develop serious medical problems later on.
Visit your local shelter. You may even find purebred cats and kitten if you have specific wants or needs.
If you still decide to buy a cat, make sure the breeder is responsible. There are many ethical breeders out there that will let you visit the kitten’s parents and provide you with all the information you need!
