I knew about the bunny thing, because I remember one of the many research papers I had to write in Grade 9 English class, one subject I chose to right about was animal cruelty, and as such, a lot of what I researched to write about dealt with animal testing for human health and beauty products - to this day, I still remember one of the quotes I read from one of the books I was mining research from (yes, despite this being the 2000s, most of us were still encouraged to research from books, and other print material, since the internet was not always reliable) was, "How many rabbits has science blinded in the name of beauty?" For what it's worth, I never buy such products like shampoos, soap, or the like that are animal tested.
As for cows, the vegans are in their corner for that.
