Human is to Feline, as Feline is to Kit. (In my eyes cats are like children <house hold> and Kits are Feline children)
there are 7 cat years to 1 human year so 7 x 12 =84 feline years
That is the correct spelling of the adjective "feline" (pertaining to a cat).
noun - canine (dog-like) adjective - ursine? (bear-like; bulky as opposed to sleek)
Feline is to cat as Equus is to Horse. Is that what you are looking for! Or check out the CAT WIKIPEDIA for more information!
