Yup, but I also test on my cats. You seem to have quite a number of them as well. They double as pets and as willing test subjects.Haha! Maybe people should respond to Haidut's lab suggestions as "I've tested supplement x on my pond of Koi" instead of talking about their rats.
They also have a hormetic effect on us. Their dander and their bacteria give us low stresses that make us deal better with bacteria and with allergies.
