Equine is just like bovine, canine, or feline. Bovine is to cow as canine is to dog. And, of course, feline is to cat. SO, when referring to the equine, someone is referring to a HORSE. Hope this helps!!
A cat is a feline, actually. Scientific Classification: They are from the class Mammalia, the order Carnivora, the family Felidae, the genus Felis, and the species of the domestic cat is called F. catus. Therefore, the domestic cat is a feline.
A cat is a feline, so if you combine a cat and a feline, you get a cat... though as felines include not only house cats, but alsothe big cats, like lions and tigers, you may be able to get some sort of inter-species cross breed, though this is unlikely.
