I'm napping and then my mom wakes me up with "I FOUND A BABY SQUIRREL."

We called a wildlife rehabilitation center and they said he can't be older than 48 hours. We're leaving him outside with a heat pad and some bedding (a soft Swiffer thing because THAT'S ALL I HAD) until the sun goes down, then if the mommy doesn't find it we have to keep it overnight and try again in the morning. After a few hours of that we'll call the place back and they'll adopt him. We named him Andy and he SQUEAKS.
