It's hard to draw people. If they don't look right, everyone notices and cringes in disgust, and babies begin to cry. On the other hand, audiences are quite forgiving of poorly drawn rodents with horribly distorted anatomy (see illustration above). That's why I draw a lot of rodents... my swamp creature, for example. What is that thing? There are so many rodents on the earth that we dare not be too critical. You say there's one that looks like that? Your guess is as good as mine.
These things I drew were supposed to be squirrels. Do they even look like squirrels? It doesn't matter. If I just call them "rodents," they're close enough. Thanks for taking the responsibility and research out of drawing, you rascally rodents!
