They died :(

Not sure what we did wrong, but our tadpoles died today. When we came back from Western NC there were only a few left, now there's none. They still had their tales, so they weren't froggies yet. Maybe some of the wildlife we see around here ate them. We've seen so many squirrels, bunnies, snakes, and bugs galore! They were barely growing too and it's been about 3 weeks! We're not very good with pets. We like em', they just don't seem to last with us.
