My cat Socrates keeps dumping his litter out of his litter box, putting his toys under the bed, and moving all my rugs. Honestly, it's all worth it when he hops in my lap and nudges my hand. I love petting and taking care of him. He is the best. Write him a letter starting in an accusatory tone, but then tell him the truth. 

Dear Socrates, 

There are some things we need to discuss. You keep dumping all your litter onto the floor. You keep putting all your toys under the bed. You even move all the rugs out of place when you get the zoomies. Honestly, though, it is all worth it when you hop in my lap and nudge my hand. I love petting you and taking care of you. You're the best cat ever!

Love your owner, {Insert name}
