Animal fats are composed of triglycerides, which are a type of ester molecule in which glycerol is bonded to three fatty acids.

[5] Many mammalian animals that live in cold regions of the globe, including both aquatic and terrestrial ecosystems, have developed a thick layer of fat just below the skin called blubber.

[6] This blubber helps these animals to reduce the amount of heat that is lost to the colder outside environment.

These foot pads are present in many animals including cats, dogs, horses, and even larger mammals like elephants.
