we dont have either a petco / or pet smart but have been to both in my travels and would not buy ANYTHING there I was there when we were looking for my feathered bappies and they so misstreated their bappies (birds) I ended up buying other peoples rejected birds that they did not want......so no pet store got my money for bappies .
On the other hand most small LFS care about their stock ........now dont get me wrong not all do . I did bird training to get birds ready for purchace and make sure the homes they went to were good ......I actually would interview the potential buyers before they could get a bappy and turned down many .......on my day of inspection (I worked as a contracter to the lps) I found a bappie with his toe bit off and bone showing . I spoke to the owner and he said he wasent paying for vet care .I offered to pay for it myself but he would not get the bird back. He said no. I said if I pay what you did for him, so you are out nada he said no. He grabbed the bappie out of my hand I followed him to a back room as I reached the back room he snapped the birds neck .....Moral to this is that the pet store is facing 100's of criminal charges they are out of business and not all LPS are good you really need to research any company you purchace any live stock from fish to puppies and as sad is that is they may even be shady ..
