Flying Creature concept, playing with wings that extend out from the elbows instead of the fingers, so the forearms would fold in toward the chest when flying. (This way, they can maintain agile quadrupedal locomotion on the ground unlike bats.) Scale similar in height to a house cat; only dangerous in large groups, of course. Weak eyes, but strong sense of smell / pheromone detection. Once prey is located, they secrete pheromones to guide others to the same location so they can cooperatively take down larger animals.
