Reddit reviews Red Fox: The Catlike Canine

Vulpes vulpes is in the Canidae family, which includes dogs and doesn't include cats. I would like to see a source for "Biologists have stated foxes are actually more closely related to cats than they are dogs".

Edit: Ok "biologists" might refer to the guy that wrote this book. Foxes might look and behave more cat-like than dog-like, but I think biologically they still must be closer to dogs. The resemblance and behavioral similarities come from convergent evolution and sharing the same types of prey and such.
