Well today, we took Casper to the vet for the for the first time today. We usually go to a different vet, but we decided to give this one a try. Right when we walked in I couldn't help but notice the whole wall dedicated to Science Diet food. I can't say I was that surprised, that seems to be a very common sight. Well, my mom decided to ask the vet what he thought about Purina and Science Diet vs. Blue Buffalo and Taste of the Wild dog and cat food. My mom said that I was interested in their nutrition, and that I had her switch the dogs and cats. Here is what he said, 1. Vet, ''There is nothing wrong with Purina and Science Diet, of course the people selling Blue Buffalo and TOTW will say bad things about these foods, they want you to buy their food. - Me, When I researched these foods, I didn't look at reviews on their websites, what kind of research would that be? Of course they would support themselves, so does Science Diet, a LOT too. I looked at several different websites, at Yahoo Answers, and of course BYC and I read a the nutrition section in a cat book by a holistic cat vetranarian . Probably like 95% of of people said that Purina and Science Diet are extremely bad for your pet, and to find foods without grain and with meat as the first ingredient. Then, I looked at the Tractor Supply, Petsmart, and Petco websites and chose the foods that I thought would be best for my pet; Blue Buffalo and TOTW. 2. Vet, ''Corn will not hurt your pet, they need the fiber and carbohydrates from the corn. They call corn a ''filler'', but really it is providing essential nutrients for your pet.'' -Me, Corn IS a cheap filler, there is nothing else to it. Cats and dogs CAN NOT digest corn, and therefore go #2 a LOT more, and it stinks really bad. 3. Vet, ''Stop feeding into this nonsense and take a pet nutrition class.'' -Me, Most pet nutrition classes are taught by a representative for a pet food company. (I saw a pet food nutrition table set up at Petco once. At the bottom of their little board with all the info it said Hills. Wow, I can't guess who was teaching that class.) I am sure there are some genuine nutrition classes out there, and I would gladly take one of those. Maybe he should come with me. 4. Vet, ''Who is paying for all this food?'' -Me, My parents, and they pay for the vet bills too. So when my cats and dogs develop all these problem later on in life from low-quality food, they can pay for that too. And, Science Diet costs almost the same as Blue, so why would we buy junk when we can do something good for our pets? 5. Vet, ''The only problem is that they poop more and it smells worse, but if you don't mind than don't waste your money''. -Me, ''The reason they poop more is because they can't digest all of the corn in their food, see the connection?'' Anyways, correct me if I'm wrong, but this guys doesn't know what he's talking about or he just wants our money. And when my mom asked if we should just switch back to Purina he said, ''Yeah......or Science Diet. This guy really makes me suspicious, and now my parents don't believe me anymore and are going to switch all of my cats and dogs back to Purina! They say, ''This guy has gone to vet school for 8 years and he works with pets everyday, he knows what he is talking about.'' How am I supposed to convince them that isn't true? I told them everything I know, and I tried to show them the cat book and several websites, but they refuse to look. I told them to think of it this way, would a wolf go out in a corn field and eat corn, or would it hunt? Ugh, I just can't believe this! Help!
