I did find some Chicken Soup at Pet Kingdom in Newton, and some Innova on 22nd St in West Des Moines. I think I'll try the Chicken Soup for 3 months and then the Innova for 3 months. That should be long enough for me to make a decision as to which one to use all the time. My babies are 2 years and 1 1/2 years old and have always been on Royal Caine.
Thanks for all the help!!!!
