You have an older brother who really likes cats

You are lying on the sofa watching TV and eating biscuits, suddenly the cat comes and it seems to want the biscuits you are eating. When you were about to give your biscuit to the cat, your brother immediately took your biscuit and ate it

"You can't give the cat any food at random."

He said calmly but strictly, then he picked up the cat and gently stroked the cat's head
