My husband used to work at Petsmart, and I recently asked him how much they fed their baby bearded dragons. You want to know what he said? TWO CRICKETS TWICE A DAY EACH! Salad all day, but TWO crickets?! He stopped working there when he learned how incredibly ignorant the people were; he wasn't one to say he 'knew' something unless he trully did know it.
Unless these major league pet stores start really reading up and training their personell appropriately, I will NEVER buy an animal from them.
I'm terribly sorry you lost him. You really did an awesome thing, and I'm sure he was super happy to finally be taken care of. Those ignorant people who said it was your fault need to be kicked in the teeth. By a horse.
I'm very straightforward, and I hope I didn't offend anyone.
See you over the rainbow bridge, little one.
