It's not uncommon for a lot of animals the general public thinks of as either cute/docile and vegetarian as otherwise omnivorous. Cows and horses are the easy one because they will quite literally hoover up small enough animals like mice and birds, but then you get onto things like woodpeckers which use their bills to burrow into the brains of larger bird chicks while still stuck in their nests.
"Nature is metal" is the subreddit/trope name for good reasons.
I'm surprised this is the first time. As far as I know, it's not uncommon for chipmunks to eat frogs, and they're basically squirrels.

Bullfrogs man. They'll eat snakes, fish, mice, ducklings, each other.
