Solid Gold is ideal for adult cats and kittens, to maintain total health. Depending on the age of your chihuahuahs, there is Hund-n-Flocken Adult Dog (lamb) and Hundchen Flocken Puppy (lamb). I have never fed Buddy the Solid Gold variety, but it sounds really good. They also have a food called Mmillennia Beef & Barley Adult Dog, it's for adult maintenance.

Solid Gold is cheap compared to IAMS. IAMS wants to make money, so they make their food really expensive. Solid Gold cares about the health of your pet and their nutrition. 15 pounds of Solid Gold cat food is $20.63, that would last 1 cat a couple of months. I have never bought IAMS, but I know it is very expensive and it's filled with everything your pets DON'T need!
