We appreciate your feedback. We could not tell by your post if you had done a gradual transition or not. We generally suggest doing a 7-day transition, as this allows them time to get used to the new flavor and ingredients. This can also help ward off against any sort of tummy trouble. We hope this is helpful. Hill's Pet Nutrition

Thank you for your review. We are disappointed to hear of your experience. While it is difficult to tell the exact cause for this change in texture, we can assure you that this variation has no impact on the nutritional value of the food. Some possible causes of the variation are the freshness of the product or temperatures the food has been exposed to during distribution. A freshly produced product can appear softer or stickier and will generally increase in firmness as it ages. Some formulas with higher starch levels, can take longer for the starch to regenerate into a firmer loaf. If you go from using an older can to a newer can, there might be a noticeable difference in texture. To meet specific nutritional needs, some of our formulas have higher levels of carbohydrates. Products with this unique nutrient profile may experience textural changes upon large temperature fluctuations. All of our products are 100% satisfaction guaranteed. If you would like to take advantage of this guarantee, please return the unused portion of the product to the place of purchase for a refund or exchange.
