Can rats menstruate?
Mice and rats are an important part of research labs. But when it comes to studying the reproductive health of roughly half of the world’s population, those little rodents fall short because they don’t actually menstruate like humans do. That is, almost all of them don’t.
Do rats bleed on heat?

How did Feynman come up with the rat experiment?
If so, the rat-running psychologists of old never heeded Young’s methods. “I looked up the subsequent history of this research,” Feynman said in his address. “The next experiment, and the one after that, never referred to Mr. Young. They never used any of his criteria of putting the corridor on sand, or being very careful.
How can you tell if a rat has an illness?
If your rat only picks at its food, or if it has stopped eating altogether, it may be ill. A lack of appetite often points to an internal illness. An apparent loss of appetite may also indicate that the rat has some food caught in its throat.
