Something in the Animal kingdom must be an organism which is capable of self-locomotion and responds to its environment. It also does not produce its own food; even herbivores don't. In other words, Animals eat other organisms and move on their own. The only single-celled type of animal is a myxozoa. Animals are eukaryotes.
To quote Wikipedia, Animals are "eukaryotic and usually multicellular, which separates them from bacteria and most protists. They are heterotrophic, generally digesting food in an internal chamber, which separates them from plants and algae. They are also distinguished from plants, algae, and fungi by lacking cell walls.

You have to be a living organism for one and not a member of Flora & Fauna, bacteria and fungi.

You have to be muticellular, eukaryotic organism that can move from place to place and you don't have cell walls or chloroplasts. You have to be heterotrophic too.

multicellular
no cell walls
obtain energy through resiration
Mobility isn't a characteristic because sponges are animals
