What to feed hopper mouse?

Maybe for your little pet mouse but you need quality for feeders.

Do you think feeder breeders feed seeds?

Too much fat too much protein but hey I only breed a few thousands of feeders each year and have done so for a decade.

Which dog food would you recommend? I'm not looking for brand names. I just want to know if food for puppies would be better or adult
