Cats Mating! D:

As I was working on my homework late this night at home I had my window opened. Out of no where I hear this like crying screeching noise outside! At first I though it was like a baby outside crying but I waited and listened more. I started to familiarize the noise with the meow of a cat...so I still waited and listened more. After a couple of minutes I just stopped paying attention and proceeded with my homework...until the crying got louder and louder. I got a little scared and wondered maybe this cat is hurt or something. So I looked it up online of crying cats at night and it turns out that the noises were mating calls for cats! Also when the noise got louder that was actually the cats mating at that time! I found similar noises online that matched the ones I heard. It kind of tripped me out because it made me think how cats are just like us, in the process of some sexual action they get loud as well! haha
