Here's Jake Smitka, 19, from Amsterdam, New York, with his friend Wilson, a baby squirrel.
The two made friends for a week and Smitka put the whole experience on Snapchat, where his followers loved it. Smitka told BuzzFeed: "I would put him in trees but he would always follow me back inside."
I'll never forget the day I met this baby squirrel. Hope you're doing big things now. You weren't just a squirrel t… https://t.co/gWmjjr5Mt7
"I fed him grapes and nuts and he drank water... And he would chill on my shoulder... he would just sit up top and look all around, especially when I drove. He loved looking out," he said.
Sadly, Wilson is currently missing in action. Smitka said: "Usually he would be waiting for me on the tree if I would leave or something but... one day I never saw him again 💔 "
However, he thinks Wilson's OK because his dad spotted him. Maybe he just needed some time to grow. If they have a reunion, we'll be all over it.
