Maubee

She's a lean, mean, sassy, breeding machine (and she's damn good at it too)! 

Equipped with more than just the bare essentials including
1. pheromone detecting antennas to seek out her next prey
2. four arms to securely grab secure her victims
3. a massive cock with venom secreting barbs
4. an extra long tail with a an extra big stinger to poison her target
^^^ALL OF THESE CAN RETRACT LEAVING HER LOOKING LIKE A NORMAL FEMALE CAT

Maubee has three venoms that she can choose from at will.
1. Numbing - renders the person helpless, unable to move for a set amount of time (one drop = 5 minutes per 100 pounds)
2. Aphrodisiac - increases arousal and strengthens feeling of stimulation (doesn't necessarily guarantee pleasure)
3. Addicting - creates (or increases) sense of need for breeding (this venom is only used for pets Maubee finds promising)

Maubee tends to prefer breeding females but isn't opposed to the occasional male! (she especially loves small femboys)
She finds males more useful for feeding. By tricking them into thinking she's a full female, Maubee numbs and bites at the thinner skin (typically neck) to suck out their replenishable life energy, which leaves the males very weak and tired temporarily.
She doesn't feed on females as she needs them to be completely healthy to carry her seed.
