Yes, they include: cats, dogs, fish, cows, elk, seals, polar bears, grizzly bears, orangutans, pigs, lambs, moose, deer, rats and mice, to name just a few.
That being said, please keep in mind that RJL does not provide software or equations for body composition estimates for any species other than humans.
To evaluate body composition in non-human species, you will need to find published equations that have been either developed or cross-validated for your study population and you will need to replicate the test protocol (including electrode site preparation, electrode type, and placement) used by the original researcher(s).
