"In the wild, a cat will eat only a very small quantity of any grain, namely the stomach contents of mice, rabbits, or birds he catches. Why then, should a pampered household cat eat a diet that is loaded with the one food nutrient he really doesn't need? . . .
Dry cat food can also contribute or be directly related to certain health conditions:
- IBD (Inflammatory Bowel Disease)
- CRF (Chronic Renal Failure)
- Urinary crystals (which are potentially fatal to cats)
- Diarrhea or other allergy-related conditions
- Dehydration (cats on canned food diets get sufficient water in their food)"
However, should the cats get ONLY canned food? Probably not. In Tips for Choosing Cat Food, Franny also states:
"Many nutritionists agree that cats should get a variety of food, both dry and canned"
Sounds like you should feed the cat canned food twice a day and leave some dry food out for snacking.
