She hasn’t reached the end of her life. Most cats die of cancer or kidney failure, many of diabetes. Kidney failure and diabetes in cats, now so common, were almost unknown before dry food. Dry food usually has less protein than they need, and is very high in carbs, which they don’t need, and which breaks down into sugars. It is also dry, depriving the cats of the high water content of raw meat. They will not drink enough water to make up for it. You have to do what you can. If he won’t eat canned food, he won’t. Our previous cat developed kidney failure at the age of eighteen. I gave him sub-cutaneous fluid infusions with a needle and Ringer’s lactate for the last three years of his life. It gave him deveral more happy years before his creatinine got out of control and he developed an inoperable oral tumor, so the vet came here to put him to sleep. Drs. Lisa Pierson and Elizabeth Hodgkins say cats do not go into kidney failure if they never get dry food. I know cats are all different. We took in a little abandoned kitten a year and a half ago, anout six weeks old. I bought queen’s milk to give her as well as canned food, but it caused diarrhea every time I gave it to her. And even when I didn’t. She had a coccidia infection, but Albon did nothing for it. I googled it and asked for Marquis paste, which the vet let me order from a compounding pharmacy. It was miraculous, stopped the diarrhea right away, but it was not the treatment my vet thought was usually effective.
