My thoughts on prescription diets (at risk of creating an echo chamber here!) is that the large majority of the time, there is a cheaper and better suited alternative if you look at the nutritional requirements and guidelines for the the condition you're looking to accommodate (e.g. diabetes, CKD, food intolerances/allergies, UT disease, etc.). I would say the only exceptions are the recovery formulas when (temporarily) necessary (Hills A/D, Purina CN) and the kidney diets (K/D NF) conditionally in late/end stage CKD. The only prescription diet that is even suitable for a diabetic cat is Purina DM--all of the others are too high in carbs. And even though it's a good food to feed, since it's pretty much the same thing as Fancy Feast, it's way overpriced.
Bandit used to be obese, back when he was about 5-6 years old. That's what happened from free feeding him Purina dry food. Our vet at the time was one of the creators of Hills Science Diet, so I thought we were consulting with an expert on feline nutrition. He put Bandit on Hills W/D dry, and boy did Bandit lose weight, all right--it caused a severe case of triaditis and subsequent diabetes diagnosis the following year. That's when I finally did research on feline nutrition on my own, and realized what I had been told by my vets all along about feline nutrition was not correct in the least.
I also made the mistake of feeding Purina NF to one of my cats when she was diagnosed with early stage CKD (it was called the unnecessarily scary "Chronic Renal Failure" at the time, and despite my experience with Bandit, the vet talked me into it). Boy, was that a huge mistake. She hated the food so it became a chore just to get her to eat at every meal, she lost a lot of weight and the low protein caused muscle wasting where she barely wanted to move. Based on the vet's feedback, I thought that this was the kidney disease progressing, but all her bloodwork was holding steady. I found some studies online that talked about the low protein/low phosphorus debate and decided to try changing her diet. So I switched her to a low phosphorus commercial diet instead, and her health dramatically improved. Her CKD never progressed past stage 1, and she was on the low phosphorus diet for 2 years before she passed away from stomach cancer.

) or feed him the dry prescription food despite his diabetes having nothing to do with why he was at the hospital (he had an accident with his tail and needed an amputation, and they happened to have one of the best surgeons in the country on call when it happened). Luckily, Bandit's regular vet was able to tell them that we had the diabetes under control, and it would be very nice if they could just focus on Bandit's tail.
