Hi, The good news is this month, Lolly is 3 years OTJ this month thanks to all the help FDMB gave me, walking me through Tight Regulation with Lantus. For past year, I've been testing monthly, sometimes more, she's been in the 50's consistently. All my cats have been eating Fancy Feast Classic since Lolly's dx. Now Lolly is showing signs of pancreatitis. Vet said it's not high, they are sending me labs via email by Monday. My vet really wants me to switch to Hill's i/d. I know she just went to a cat nutrition conference hosted by HIlls, she was very upfront about that. She says she was very impressed with the quality and batch testing they do. She's been Lolly's vet for a while, and otherwise I think she is an excellent vet. I told her the different values from Dr. Lisa's chart, that Dr Lisa is a vet, but she still wants me to do the i/d. She says Lolly needs lower fat content. I've looked at Dr. Lisa's chart and here is what she lists for FF and i/d: FF Classic: (in percentages) Protein 38 ; Fat 55-60; Carb: 2-3 Phosphorus 380 mg/kcal Calories per 5.5 can ~90 Hill i/d : Protein 30 Fat 47 Carb 23 Phosphorous 203 Calories per 5.5oz 161 Fat content doesn't seem much lower, but the Carb is much higher. Phosphorus and calories are the big differences. Any reason I should switch her to Hills i/d? Could it send Lolly out of remission? Thanks for any advice.
