Kids paying rent?

I didn't when they grew up and stayed at the house, but my oldest daughter came back after her divorce and tripled our utility bills (both water and electric) as well as having my wife spend enormous amounts of money on food for her three German Shepherds. When my boys said the dogs ate better than they did, I started paying attention. She was feeding them huge rump roasts. Yes, dogs are being fed raw human food. My wife was allowing this because she has zero idea about the value of money. She only worked for a couple of years in her early 20s before finding someone who made enough money so she could be a sahm. She lived with us for almost a couple of years until we had it out. She was bragging about how she was able to live her lifestyle, pay all her bills, care for her 5 pets, etc. That's when I flipped the light switch on and off, did the same with the kitchen sink and stated that the number one expense an American has is the roof over their head, water, electricity, garbage, sewage, taxes and she wasn't doing any of this. She was insulted by this, moved into an apartment with her loser boyfriend (hobosexual) and was immediately hit by reality when he couldn't pay his half of the rent the first month that they were together. She was still visiting our pantry late at night to "shop" for groceries and personal items like toilet paper, toothpaste, detergent, etc. I worked nights at the time (got home around 2 am), and my wife and the boys were often in bed by 10 pm. She'd stop by, leave virtually every light on on the ground floor, and take many stuff that my wife had planned for dinner the next day. We never charged her rent, but man I really wished we had not made her so entitled when she was in her early 20s.
