I stay away from Science Diet even though my vet suggest it from time to time in a very low key lukewarm manner. She knows that I'm not going to put up with that stuff. We feed Evangers, Wellness, Earthborn, Prowl.

Personally, reading the ingredient list of Science Diet makes me cringe. Many of our cats have medical issues yet we manage just fine with the brands I've listed. One is a 14 yo. His number is still okay but always a concern. Next one is a 10 yo who is starting to have arthritis and is now on glucosomine supplement. three others has auto-immune and another has urinary tract problems often and gets blocked from time to time. All were recommended to be on special diet of one sort or another but all are doing quite fine with the premium food.
