I have spent a portion of my life memorizing all the extant felids, in lineage no less, as well as their taxonomic classifications. This treasure trove of information has the side effect of creating oddities in reading them or viewing them as consequence, however. For example, I can no longer simply attend a sanctuary or reserve and not see a marbled cat and think to myself "Ah, [i]Pardofelis marmorata[/i], of course."
