Stacked colorful cartoon cats with big round eyes

Create a stylized, cartoon-like image of several cats stacked on top of each other, peering upwards. The cats should be different colors: black, orange, purple, green, pink, and beige. Each cat has large, round eyes with different colored irises. The style is flat and graphic, reminiscent of a children's book illustration. The background is a solid teal color. The lighting is even and diffused, with no strong shadows. The composition is a close-up, vertical shot, focusing on the cats' faces.
