I can’t express the success of this cat food formula. It’s saved a constipated cat from having to be flushed every two weeks and $$$ at the vet. After eating this product, just for three days, he started to have regular bowel movements. I continue to mix this now with wet and other dry and it still works in smaller doses. What I don’t understand is why retailers have shot this product up from $46 a bag to as much as $150. At least I was able to get a price around $100 at Cozzzy. This is a fair price, but I’d prefer to pay < $80… additionally there is new signage on the bag and packaging, I’m comparing the ingredients and it appears to be similar, but not exactly as the original formula. Fingers crossed, I hope when the brand was purchased by Mars Inc. they will honor the intention of the original product.
