What is the narrowest taxonomic classification cats and dogs have in common?

Don't say mammals. Even I know that.

1. Order Carnivora
2. "Mammals" isn't the taxonomic term. Anyway, cats and dogs are both in Order Carnivora. After that, cats are Family Felidae and dogs are Family Canidae. http://en.wikipedia.org/wiki/Cat http://en.wikipedia.org/wiki/Dog (The taxonomic classifications are under the pictures on the right.)
3. Cats and other cat-like mammals (e.g. civets, mongooses, hyaenas, small and big cats, and sabre-toothed cats) are classified in suborder Feliformia within the Mammalian order Carnivora. Dogs and other dog-like mammals (e.g. weasels, bears, giant panda, raccoons, skunks, seals, sea lions, foxes, wolves, otters, and the lesser panda) are all classified in suborder Caniformia within the Mammalian order Carnivora. Therefore dogs and cats are both members of Carnivora, the least inclusive taxon one can find that includes both dogs and cats. The whales and dolphins are not members of the Carnivora, but they are more closely related to the hippos, the cows, sheep, goats, camels and pigs, all members of the mammalian order Artiodactyla.
4. Carnivora
5. Suborder. Unlike Cal King, though, I would put them in suborder Fissipedia, the carnivores other than the seal-like ones.
