As I life long cat guardian, I have had a few felines who preferred to eat only dry food. One, my beloved Siamese Bubba, developed stones and a urinary obstruction that required emergency surgery. Here at St. Francis Animal Rescue, we have several cats who are dry food addicts. There are concerns over this diet as the water content is low and the carbohydrate load is too high. The dry food protein is often from more plant based grains than animal based source. We all know cats are obligate carnivores and not the best water drinkers. They will drink some water from their bowl but can get considerable moisture from eating wet, canned food. Again, the danger of too little water is urinary tract infection or the formation of stones and possible fatal obstruction of the urinary tract. If at all possible, a dry food addict should be slowly to eat small amounts of wet food daily.
