About BLUE Buffalo

Blue Buffalo began with unconditional love and some furry inspiration from a large breed Airedale, Blue. When Blue's family started a pet food company, their vision was clear. They wanted every pet parent to be able to feed their pet with the same care they would feed family. So they created the #1 natural pet specialty food to help furry family members live happy, healthy lives. Of course, they named it after Blue.

oops, I meant how many cups in a 6.5 lbs bag
Answer by ChewyJan 21, 2019
The 6.5-pound bag of food contains approximately 32.5 cups of food, and the 16-pound bag contains approximately 80 cups of food.

Is the 16 pound bag resealable? It was mentioned in a previous question that the 6.5 was but it didn't mention the 16 lb.
Answer by ChewyApr 09, 2021
The 16 pound bag is not resealable.

Does this help with calcium oxalate as well as striuvite crystals? I've heard some only help with striuvite
Answer by ChewySep 30, 2021
The W+U Weight Management and Urinary Care formulas were created specifically to help support healthy weight loss in cats as well as limit the formation of struvite and calcium oxalate uroliths.

Prescription cat food

As always, ordering and delivery was pleasant. Of course, the cat is VERY fond of the boxes. We have a 9 month old male. I have always had females due to the many male health problems but my housemate fell in love with him. The vet prescribed a Hills formula. I researched it and was not impressed by what I found. Have used the Wilderness products for years and was thrilled to find they have the perfect formula. Better ingredients for half the price. Thanks!

Fantastic replacement for other prescription urinary food - no more throwing up

My cat had urinary surgery two years ago and after a few months on Royal Canin Urinary SO he started throwing up every time he ate. Over time I became convinced that it was the corn and wheat in that stuff causing the problem, since one of our other cats also started to lose fur all over her body (really hard to separate the food, so everyone eats the same stuff). Finally got my vet to agree to prescribe this and BOTH issues, the throwing up and the fur loss, have been resolved. I do combine this with a holistic dry food that has some grain in it, just not wheat or corn. This Blue Buffalo formula is AWESOME stuff.

Love, love, love

My cat is a grazer but that doesn't matter because he loves it. His coat seems very shiny and there is no more dandruff. I'm very pleased with this product. Thank you.

Excellent Food Product

Vet recommended for weight reduction in my ten year old male cat. In addition, you get the benefit of urinary tract health maintenance. Hoss loved the food from day one of introduction. One month in and he has dropped one pou d, his fur is much healthier, and transition occurred without stomach upset or disruption in feeding.

Good Entry into the Specialty Market

A first for this brand to enter the pet special diet market. I am mixing this with other established brands to provide a choice for my kitties who need weight management and urinary tract care. It's really tiny kernels of food. So, if your cats wouldn't mind this sizing, you may want to try. My cats seem to like it, as they don't eat around it.

Blue Buffalo Natural Veterinary diet

This product is amazing! Was feeding all grain diet and cats seemed to be gaining weight and not as playful. So decided to switch to Natural grain free and more activity, coats are shiny and they seem to be not as hungry. Have only been feeding this product for about three weeks but I see a complete change in my 7 cats. Do recommend this product!

Transitioning to a new food

So far, the transition is going well. There has been no GI upset. We are hoping this will also lesson the skin dryness and itching currently experienced.

Apparently tastes good

After both my cats had urinary tract incidents when I tried to switch them to diet food, this one has turned out to be a winner. We went through several other brands via the vet that they wouldn't eat but they seem to like this one almost as much as their ultra high protein high fat former diet.

Great Product!

My cat wouldn't eat any other rx food because it wasn't grain free. This food is a blessing! We will see what his urine test shows in 6 months when he is tested for his stones again ...stay tuned.
