This was pretty nice.
The simplistic background helps save a lot of work. Paper works well for this one. I really liked how when the power device was turning it seemed kind of 3D-ish which was neat.
The story was kind of iffy. I felt sad for the cat when they left due to being annoyed by the dog. Then they figured out opposable thumbs and began to take over humans and get food. When it no longer worked, cats got angry instead. Warmed my heart a bit at the end seeing the person still liked the cat after all that happened.
Overall, underrated I think it will be.
