If only we were plants. It'd be so much easier to get energy and bypass insomniac issues and such.
We're aware that humans are also an animal, but we're trying to shed some light on the people who're drawing non-human animals (I wasn't the one who made the group, but I'm pretty sure that's the intention the original creator had in mind). Speciesism does suck (in my personal opinion), which is why I generally don't include it in my own stories and such, but human artists dominate the majority of the artist community which leaves less room and appreciation for people who don't (or can't) draw people, but instead draw animals.
I hope you understand!
