What is the book about a boy living underground with animals?

featherflower19: What is the book about a boy living underground with animals?
Years and years back, I read a book where a little boy runs away from his family and lives with animals in an underground burrow. I can’t remember if it was raccoons or groundhogs or what, but it was about him learning to live with them and avoiding being found by humans because he doesn’t want to go back home.
Any ideas on the book title would be greatly appreciated. I really want to find this book again!
