Stop feeding the cat dry food. I just recently found out how bad dry food is for cats--it dehydrates them, and causes urinary and kidney problems. Most dry foods have too much carbohydrate and too little animal protein. Even the so-called prescription foods are bad for them; just read the labels and you'll be amazed at the stuff that's in there that is no good for cats, like corn, potatoes, carrots, etc.
Cats are obligate carnivores and need animal protein, not plant protein, not vegetables, not grains, and not fruits.
My six cats are doing so much better since i stopped the dry food, but the one with pancreatitis and CKD still has to take antacids to help with acid stomach and nausea. I also add slippery elm bark to his wet food, which also seems to help. There are a lot of sites on the web that deal with specific problems like kidney disease in cats and pancreatitis--this is how I found out how bad dry food is for cats.
I'm thinking of changing to raw foods, but since I have six cats, it's problematic, because 1) I don't have the time and 2) I don't have the freezer space.
I've been feeding them Instinctive Choice, by Life's Abundance, which has no additives, grains, vegetables, fruits, etc.--all those carbs that cats can't digest. Cats are so different from humans, or dogs.
My cat with pancreatitis tries to eat dry food, but ends up throwing up every time, so I only feed a little as a snack/treat to the other cats, and the rest of the time they get wet food. Some good foods, though by no means perfect, are:
Life's Abundance "Instinctive Choice"
For dry food, "Young Again" has the most protein (50%) and is supposed to be very good. Life's Abundance Dry food is okay, but contains brown rice, and is only 30% protein.
