You can always feed two. Just wait until the first is down in their lower half. My girl is in the middle of what size f/t feeders I can get right now so I just thaw 2 and she's been taking them both. I heat one, offer, wait for her to get it mostly down, and heat the other up. (They're room temp when I get home to feed her, I set them out a few hours prior. Hot water submersion in a colander and bowl w/ a weight on the baggie to heat.)
