We'd say we've never heard anything like this before but we've seen Joe when there's pizza around...though, this is about a million times cuter. 

Boo the pet otter gets so excited for food, he actually makes these cute little squeaks and cat-like noises you'd have to be a monster to ignore!

This really makes us want to get a pet otter and we don't know the first thing about how to take care of one!

You could be just as cute as this little guy but you probably shouldn't try or you'll just look like some creep who lives in a van...
