It deserves notice that it is of no importance to a very young animal, as long as it is nourished and protected by its parent, whether most of its characters are acquired a little earlier or later in life.
Kontuan hartu behar da animali kumearen kasuan, amaren umetokian edo arrautza barruan dagoen bitartean, edo gurasoek babesten edo elikatzen duten bitartean, ez diola ezer axola bere ezaugarri gehienak lehentxeago edo geroxeago lortzeak.
