The common wild toad has much the same diet the world over. There are a few species of toads that will eat dead animals and even dog or cat food, but for the most part they eat living animals. Depending on the size of the toad the food they will eat varies. To see what small toads eat see the post entitled what do small toads eat. Most wild toads will eat everything from small spiders to large rats. This includes birds, worms, ants, lizards, slugs, snails, butterflies, crickets, centipedes, most invertebrates, and even other frogs and toads.
