Questions About the “Woman Yelling at a Cat” Meme

Now that I've seen the "Woman Yelling At A Cat" with 147 different funny sayings on them, I just had to do some googling.

Apparently the "yeller" is Taylor Armstrong having a meltdown on an episode of "The Real Housewives Of Beverly Hills." I didn't read far enough in the article to find out who she was upset with. I do not seek unneeded drama.

Now, questions. I have many. Whose cat is it? Was he randomly picked because they needed a cat to yell at?

Do the creators of all of these memes make money doing this? If so, how?

Is there a way somebody like me could make another one of the yelling/cat memes and add my own words?

Yes, these are truly the things that I think about all day.
