Thank you! I sent the letter at the beginning of July, and got the response a week or so later. So it was quite a while ago. Unfortunately the few times I've stepped into Petco since then it's still been horrible, with dead Bettas everywhere and black fuzzy junk in their cups. I don't know if this only applies to Petsmart stores in my area, but they have GREATLY downsized their Betta section, and (besides being in tiny cups) the water conditions are looking acceptable. I now refuse to buy from Petco, and mostly shop at local pet stores, although their Bettas aren't really looking much better than the large companies. I wish I could find a store that was local AND took care of their animals, because then they would get all my business.
Kindness and respect should be shown to all animals, no matter if they are furry, scaly, big, or small. Be a hero to the animals and GO VEGAN!
