Bro, no way a human wrote this article. Even the name screams suspicious—like a committee of mice sat down to craft a human alias. They’ve only ever seen a “cat” and another mouse, so they landed on Katie Moisse.
The scientists probably said that, compared to mice on a specific feed, mice who eat a simulation of a natural diet, and ones with yogurt added to their diet, the ones with yogurt averaged less fat, and had more mates/sexual interest.
Person wrote the articles about this, hands it over to whoever makes headlines, and they, in a bid to get attention, wrote the results in this manner.
