An orphaned baby squirrel was placed with a nursing mama-cat. We’ve read the science that talks about the mechanisms that cats have to purr. But could it also be something that’s learned, perhaps from a nursing mother cat? Listen carefully at the end of this not very long video to hear the squirrel’s purr. We know that some other animals, like rabbits, make a purring like sound by rubbing their teeth together. But that’s not what the baby squirrel sounds like, it’s more of that motor boat sound we love that comes from our cats!
