I have a frog guest for this winter. It moved in with my giant cactus plant. We haven’t seen it, can’t testify to tongue length but it sings like somebody running their thumbnail along comb teeth. Missouri Conservation agent said it must be a comb frog. Imagine that. I have a small dish kept full of water in there and feed it works. We have had a cold and nasty winter so far this year. Froggies songs keep spring alive. I love animals, even invisible ones.
