Foxes are the most cat-like of the canines, having semi-retractable claws that allow them to climb in ways that other canines cannot.
Foxes have a very wide range of vocalizations. They scream, bark, whine, trill, growl, chirp, chirr, and many more. Often they are used to express various emotional states. For example, our Roxy will whine with her mouth wide open when she wants her friend Monty to leave her alone!
Red foxes have black-backed ears and white-tipped tails. Grey foxes have more variation in their ear color, but black-tipped tails.
