Since we are on the subject, my baby is about 15 years old now (I had to work for that). I've been feeding her dry Iams for her whole life. Peanut has always been pretty chubby and I'm noticing now as she gets older she's getting chubbier. Do you all think it would be OK to switch her to canned food at this point? I would like to get her weight down. I only have her so I can regulate the food supply easy enough. Are there any specific canned foods that are better for older cats like her?
