The first time we went to the store was to get a betta fish and a baby hamster. Unfortunately the hamster died after a few days. I called the store and told them what happened and how upset my 10 year old was. I was told there were other baby hamsters that died from the same batch. They advised me to come to the store so we can get a replacement hamster. When we got there, the staffs were very apologetic and helped my son picked a new hamster. We got a 2 month old bear hamster which we named Baluu.
