This food has turned our kitty's health around. She was diagnosed with severe IBD after her blockage surgery. Her coat is coming back thicker, we are seeing less hairballs, and she gained back the weight she lost while sick. There is one unfortunate downside to the food. Her poop REEEEEEKS now. It's unbearably stinky. We follow the restricted diet recommendations and her poop looks normal, it's just so stinky. We are willing to deal though as her health is more important than our sense of smell, hence the 5 stars. Unrelated, but I would just like to mention that some of the brand's responses to other reviews that aren't 5 stars, aren't the most professional. Unfortunately, they come off passive aggressive and has left a bit of a bad taste in our mouths. Otherwise, this brand makes a wonderful choice of food for IBD kitties and we will continue to purchase this food for her. Thank you for providing this!

My review is long over due. My CKD IBD kitty refuses to eat any wet food which would be ideal with CKD..Young Again Lid Zero Mature was suggested on a CKD page that I follow as it’s low phosphorus - super low carbs and higher protein to avoid muscle wasting. Mischiff is super picky …..and he absolutely LOVES this kibble. I know it’s a much healthier option for him than his old kibble and even the RX kibble (which he won’t eat either!!!!) When my girl was end stage CKD the only way she would eat her wet food was with some of this kibble smashed up and sprinkled on top. The people at YA are awesome to deal with too…great customer service.
