Oh dam you're right, both my sixth grade biology book and my AP biology book have it down as felis domesticus, but felis cattus is correct as well. Which is funny taxonomical classifications derived mostly from Greek and Latin usually don't resemble the common name of a species in English, English also has Germanic roots dogs (canis lupus familaris) aren't canis dogus.
Data gives off the impression that he understood art a lot better, because his paintings seemed quite nice, but of course being an android his realism would be amazingly precise, as for other styles of art, it would be a simple matter of picking out the patterns of said art, maybe combing them with others. But when it comes to something like evoking a feeling with something as structured as a written language designed with the purpose of communicating ideas effectively it makes sense he'd struggle with creating his own.
However any cat lover might disagree that he failed entirely, in evoking emotion with his poetry, show that he "enjoys" observing Spot and he has come to appreciate her intelligence, just my opinion.
