Jewish Dietary Laws

In Exodus 23:19, Exodus 34:26 and Deuteronomy 14:21 States: " Do not cook a young goat in its mother's milk." What is the explicit reason for this instruction of not cooking a goat this way and given as a command when G-d gives it THREE times? Thank you for the research...I hit a dead end in mine.

Do dairy and meat waste need to be thrown in separate trash cans?

I’ve always understood that a lot of cheese is not kosher because it contains animal rennet, which constitutes a mixture of milk and meat. Kosher cheese substitutes enzymes. But in recent years, I have found a lot of certified kosher cheese on the market that lists “rennet” as an ingredient. In fact, some of it even says “animal rennet.” This is all while these products are certified by some of the most recognized hechsherim. How is it possible that cheese containing animal rennet is really kosher?

How long should I wait between eating meat and eating dairy. Thanks.

Is a giraffe a kosher animal? I've never heard of it on the menu.
