The convention's definition of torture is extremely narrow. It excludes acts of torture committed by individuals in a personal capacity, except in cases where there is some government, or official, complicity. The concept of torture as an international crime is correspondingly constrained. Drug offenses.
During warm months, catching local insects (nontoxic, of course) can provide added variety. Moths seem to be particularly relished by most toads. In the wild, they eat grubs, spiders, worms, insects, slugs, snails and other invertebrates. If your toads are wild-caught, try offering them what they eat in the wild. Adult toads should be offered three to six food items every other day. Toads under an inch in length should be offered appropriately sized food items, such as flightless fruit flies, pinhead crickets and other tiny insects.
Since toads are carnivores, they prefer to eat insects, worms and other types of live prey. Baby toads are often quite small, especially right after they have undergone metamorphosis from the tadpole stage. That can make it difficult to feed them, though there are a number of insects that baby toads can eat.
