I think it's good to give them a little variety. Think about it....would you want to eat the same thing every day? The food I use comes in 4 varieties and I change with every bag. I also use some canned mixed with dry for their evening meal. The canned I use comes in 3 varieties so mine actually get 12 different flavor combinations without changing formulas. Mine aren't allergic to any of the protein sources and there's no stomach upset with the changes. They seem to really enjoy their food with no pickiness. |
