Answer to Question 1
Hedgehogs are insectivores and nocturnal. They feed on insects, worms, snails, bird eggs, and small
invertebrates such as frogs and snakes.
Foods formulated for hedgehogs are now available in some localities. These would be the preferred diet.
If these formulated foods are not available, good-quality cooked beef and poultry cut into small pieces are
favored. Other foods that one can try feeding are dry kitten or cat formulas. The commercial foods can be
supplemented with some small pieces of fruits and vegetables. Hedgehogs love mealworms, wax worms, and
crickets. Feed the worms and crickets primarily as treats, two or three at a time, every two or three days.
Answer to Question 2
When the animal comes across a new smell or object, it licks at the smell or object, producing a flow of foamy
saliva. The animal will then stiffen its front legs and swing its head from side to side. Using its tongue, it spits
and smears its spines with the saliva.
The reason for this behavior is not known. It may be a form of protection from predators or a method of
attracting a mate.
