PSA time. If you see animals obviously being abused or mistreated or even just mishandled or sick, DO NOT BUY THEM. Even if you want to "rescue" it from its abusers. You are perpetuating this poor treatment by giving the store money and keeping them in business. They don't have any incentive to clean up their ways if they are making money doing things the way they've always done them. Don't buy a pet just because you feel sorry for it -- think of all the dozens or even hundreds of animals who will suffer because you subsidized a cruel or ignorant pet shop with your purchase.
That said, it can be a fun place to browse, just not buy. Though I try really hard not to look at the poor bettas in their tiny cups and their nutritionally bankrupt supposed betta food.
The sugar glider food is also nutritionally imbalanced and promotes cherry picking by the faster eaters. Who the hell feeds gliders -- heck, *any* animal -- SPAGHETTI-O'S? They're PEOPLE FOOD (Though I wouldn't even feed them to my kids)!
The fact that they get the nutrition dead wrong for the two animals they have in their shop that I know the most about doesn't give me confidence in their knowledge or husbandry for any of the other species in their store.
Some of the workers are nicer than others; it all depends on who's on shift when you go there.
They don't let you handle animals unless you're buying them, but how can you know for sure you want to buy them until you play with them? I understand they want to protect themselves from all the looky-loos but what if you're a serious buyer that is then disappointed that the animal you've been shown turns out up close to be unhealthy or otherwise not the right pet for you?
Buyer beware: they're not knowledgeable about their animals and will just make up stuff -- like the ages or dietary needs of the animals -- if they don't know the answer to your question.
