Guys, these cans from Trader Joe are often only 39 cents and the birdys love it! i think it is tuna by-products because the cans say "for pets only" and it looks like a mishmash of tuna parts. still, it is protein for my girls and they need lots so they can lay an egg a day! If you have a Trader Joe store near you, go to their pet food section. Plus, this is probably the healthiest pet food out there since it is just tuna, no additives..
