Thanks for all the laughs, everyone!
Anyway, to answer the ORIGINAL POSTER (spelled out, not abbreviated, per rules, *suck up*), I understand how hard it is to ignore the convenience of Oxbow being available at PetSmart. It really all depends on YOUR values. What YOU do on YOUR own time while you are away from this forum is all on YOU. I've talked people into buying Oxbow instead of Hartz while picking up Cavy Cuisine at PetSmart.
Why do I sometimes buy it from PetSmart? Because it's across the street from my college campus and on my way home. Why do I NOT always buy it from some other place that doesn't sell animals? Because I've got commitments. And stuff to do. And if those commitments take me past the places that sell Oxbow Cavy Cuisine, then by all means I'm going to unstrap my son from his car seat, pull him into that place kicking and screaming because he wants to GO PLAY and "No get piggie pood!"
Besides, it saves me a whopping $3.72 by getting the 10 lb bag at the exotic animal hospital WHEN THEY ACTUALLY HAVE IT in stock, so I actually have to call first -- and imagine that, they're on my contact list in my cell phone -- as opposed to buying two 5 lb bags that they sell at PetSmart.
You know what else I buy at PetStupid? Carefresh. I use so little of it at a time, but because Wal-Mart is retarded and only sells their brand of Carefresh in small bags, it ends up being CHEAPER to buy the largest bag of Carefresh from PetStupid -- always with a coupon. Why do I always have a coupon? Because I took every single "Save now" coupon off every single bag of Carefresh they had at PetStupid one day. The young guy who handles the small animal department on the days I frequent, only laughed and said he didn't blame me. I asked him if he thought that might discourage people from buying pets/supplies from there. He said it might, and grinned. Then we played with the piggies for about 10 minutes.
Yep, I'm selfish. I like convenience and saving money. But hey, the cost of Carefresh offsets the same price savings buying Cavy Cuisine from the vet! So, on those days that I have things that bring me past where I can get stuff from places that don't sell animals... and if I actually have money... yep, I'm all for that. But my view, personally, is that buying supplies from a store, they see you are buying supplies. They always ask if I got my pigs there. I scoff at them in disgust and chew them out. I've never been kicked out yet! I've had discussions with people behind me in the checkout line buying Carefresh for a bunny, or some other small animal. I drop names of shelters and tell them all the sad stories of sick animals that usually come from pet stores. They agree they wouldn't even get fish from that store.
Do I feel guilty when I buy from PetDumb? No. Should I? Maybe. I'm more on the fence. I really think that buying just supplies there is okay. There is a supply and demand for supplies. There is a supply and demand for animals. The demand for supplies goes up when the demand for animals goes up. But if the demand for animals goes down, and the demand for supplies goes up, it should send a different message to the number crunchers.
