Bests & Worsts Reviews from Amazon

The Canidae product from Amazon seems ddifferent from the Canidae sold at pet stores. For the second time in 5 months we purchased a bag of Canidae Grain Free Chicken from Amazon. For the second time in 5 months both our cats got sick, and eventually refused to eat this product. The first time that this happened, in January 2018, the cats were sick for a few days. After taking the cats to the vet, we eventually put both cats on a medical diet for a few days, and both cats got better. Not knowing what had happened, we decided to dispose the Canidae we had bought from Amazon. We bought another bag in late April, and as soon as we gave it to the cats, again they were sick, with one of the cats refusing to eat it from the beginning. Since out cats have been eating Canidae bought at Petco for 2 years without a problem, we purchased a new bag at Petco and tried our luck again. It worked perfectly, the cats started eating again, and neither of them got sick. The pebbles inside the two bags seem to be a different color and a slightly different shape (more rounded and flat the Amazon's Caniday, versus more squared and thick the Petco's Canidae). Whatever the reason is, this was the last bag of Canidae we purchased and will be purchasing from Amazon. Please, be aware.
