What is a one-sentence summary of the following article?
When hedgehogs feel scared or threatened, they curl up in a ball. When your hedgehog uncurls from a ball in your hands or on your lap, it means it’s feeling safe, so you’ll want to reward that behavior by giving it a treat. Over time, your hedgehog will start to associate spending time with you with safety and rewards. Keep the treats nearby when you’re handling your hedgehog so you’re able to quickly reward it. One of the best ways to win your hedgehog's trust and affection is to use treats that it will love and want more of. Since hedgehogs are insectivores (insect eaters) in the wild, freeze-dried crickets and mealworms are a great treat to use while you’re taming your hedgehog.  You can find freeze-dried crickets and mealworms online or at your local pet store. If you don’t want to use crickets and mealworms, you can give your hedgehog small pieces of fruits and vegetables like corn, apples, and carrots. Hedgehogs are susceptible to obesity, so you’ll want to make sure you’re not giving your hedgehog too many treats. While you’re taming your hedgehog, stick with 2-3 treats per handling session.  If your hedgehog looks like it’s gaining a lot of weight, reduce the number of treats you’re giving it every day. If you can still see your hedgehog's face, ears, or feet when it curls up in a ball, it's a sign that your hedgehog is overweight.

Summary:
Give your hedgehog treats whenever it uncurls from a ball. Provide treats that hedgehogs love as rewards. Avoid giving your hedgehog too many treats.
