Meat. Lots of it
Ah, if it is the human shape with the down arrow, first go to Shadowed Curios and purchase the 'glasses', next 'wander' around the city, mall, park, or curio until you encounter a 'short' woman. Use the glasses on the woman for a food hint and offer them food, if you chose the right food, you can have them follow you to the alleyway to feed them to Cici. Afterwards, Cici will give you another vore hint. You can check the image files for more hints for the drawings in the Big Aspirations 0.7.4 folder = Big Aspirations 0.7.4 > AI > Walk > Catgirl > drawings.
If the person is in Shadowed Curios, you can hunt around for them without using energy by browsing the shelves and then clicking finish shopping, as long as you don't leave Shadowed Curios, you can continue to cycle this until you find the person that satisfies Cici's craving.
At the mall, going to the casino and leaving rerolls the encounter chances for the clothing store, food court, cinnamon swirlies, and wander options without using energy. Just make sure to hit the undo button if you don't encounter the right person in these other four locations as leaving them normally will use energy.
