It's that time of year for our Best Of's - listen back to our best nature and animal stories of 2023! From the resurrection of the wholly mammoth to giraffes that do math, squirrels that sniff out more than nuts, goats that help fight fires and why chimpanzees gesture - this is the best wrap of wacky world animal stories you'll hear anywhere. Plus have you heard the beautiful - if not a little weird - sounds of the ocean? Or the giant seaweed blob that was headed for Florida? And if none of that appeals - two words: cat vaccine. But this revolutionary innovation is for your cat to take, not you!
