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.

Does this help with calcium oxalate as well as striuvite crystals? I've heard some only help with striuvite

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.

persciption food

So I have to say right out the gate that chewy is the best company. I think at this point in the world that I have experienced with dealing with problems. I do have a problem with this food and I am really heartbroken. I didn't open this last bag because by the time I got it and figured out what was going on. I'm constipated my kids the food so bad that they weren't pooping. They also were not urinating and my one cat started to go down hill pretty quickly. I almost had to take her to the ER but we got through it and she didn't have to go to the emergency. And see that which would have been very costly. I can't use this food anymore. It constipates the kids and it is just not good very disappointing all of the veterinary foods that I have tried except one that I haven't. Tried yet have made my animals sick so I'm not gonna do it anymore so I've got this full bag not opened at all. I'm thinking about asking them if I can return it and get the food that I'm using right now exchange it somehow or I don't know. But anyway long message?

Just what the Doctor ordered

Kitty loves it & it's healing him of struvite crystals. Of the approved Prescription Urinary Dry foods out there, I believe the ingredients are 1 of 2 of my top choices

My Vet recommended this for for my male cat who had a urinary infection. So far he likes it and it seems to be helping him.

I was hopeful...

My Parker has a history of urinary tract issues with both struvite and oxalate crystals. Trying to find a food with meat as the first ingredient was a task, but I hoped this would be the answer. I was so wrong! Parker now has a UTI, with vomiting! Have gone back to a previous product to get him back on track.

My cat is on the Urinary Care wet and dry food. I wish the SO wet food came in another flavor, because he loves the gravy but not so much the morsels, He loves the dry food and drinks a lot of water.

Worked wonders for my boy and all my cats love it

in 2015, my then 3 year old male orange tabby Brook, experienced a urinary tract blockage. $4,000+ later he went on Royal Canin and Hill's prescription urinary tract food both wet and dry. Almost a year later he was blocked again...another $1,500 to unblock him. I happened to be at the vet to pick up more of this food that really didn't help...when a representative from Blue Buffalo was there with their W+U prescription food. I bought cans and a bag of dry food right then. Brook and my two female cats have been on this food for the last 7 years and there has not been a recurrence of a blockage. I will never go back to the other prescription foods. Fortunately my vet will write a prescription for this food. Some vets are so indoctrinated by the prescription food monopoly that they do not.

Weight Management but cats love the taste

I have one overweight cat and the other one has grain allergies, so this cat food meets both of their needs. Amazingly, my allergic cat isn't overweight, and she is very finicky, but she loves this food.

Picky Cat Likes It

My cat has become very picky about food. Right now he won't eat any canned food. He is eating the dry food. I'm so glad my vet recommended Blue Buffalo W + U !
