I think its the store chain ..management where ever to give their employees a correct basic knowledge of pet care of the pets they sell to the public.., Its the customers responsibilty to get more in depth understanding of a pet prior to purchase. look at the efforts that go into buying a car or a computer or refridgerator for that matter..Any one who has the inclination to buy a pet from a general pet store surely should know that they need further research and understanding. With the internet so easily accesible it takes just a matter of moments to research any animal on this planet. All animals can get sick..from stress and changes thats why its soo important to learn how to make their transition as stress free as possible to help keep them healthy. the store cant be held responsible for a customers negligence .
