Mammals. (I hope I correctly read "nsulating" as "insulating.) If not, ignore this.

Explanation:

Reptiles (snakes, lizards, and things covered in scales), amphibians, (frogs, toads, salamanders, and such), and invertebrates (boneless things, like insects and octopi) don't have body hair, leaving mammals as the only viable option.
