@kitty09 - Sometimes I wonder if he wouldn't like something else.. He eats it, but I can tell he wouldn't mind maybe a little more flavor.
@BabyGirlRosie - Samples are a good idea.
@Brister - Thanks so much for the info. You summed up everything for me with your posts. I feel better now.

I didn't even think of looking up the differences on google. Thank you. He seems to kind of like the chi stuff actually. Wonder what the flavor difference is.
P.S. I'd never feed him Pedigree.
I'll see about samples of the ones you guys mentioned. I want him to enjoy his food as well as much as I want it to be good for him.
