i actually put a lot of thought into this character so here's some more info:
•She enjoys absorbing insects' energy and nutrients through her tail. (Although she is able to eat normally.)
•She blinks whenever her tail snaps shut on reflex. (This is an individual quirk, not a species-thing.)
•Her skin cells (under her fur) contain chlorophyll. Otherwise her coat would be a dead yellow color.
•Predictably, when she gets sick she turns a sickly yellow color.
•While her specific age is unknown, it is known that she is fairly young. Her tail would consist of multiple full-grown fly traps if she were an adult. (Hence the sprouting fly traps growing at the base of her tail)
•The whole cyclops thing isn't a plant-cat thing either. She is just a freaky mutant. (All plant-cats have cross/plus sign shaped pupils. Generally, females have crosses and males have plus signs. (The exception being a sex-chromosome mutation such as XXY or XYY) Her single, giant eye tends to give her migraines and weird looks from strangers.)
i might make more examples of different types of plant-cats. i have no idea if this idea has been done before i hope not!!
