1. Bribe cats by making them characters in your writing and promising NEVER EVER to do them in. (Cats are suckers for fame and attention.)
2. Give cats lists of chores to do while writer is at day job earning the $$$ that buys the cat food. (Be resolute. If the cats don't do the chores, they don't get done. Corollary: If it's dirty today and you clean, it will be dirty again tomorrow. If you don't clean today, it will still be dirty tomorrow. So forget it and write instead. Or, as Joan Rivers said: "I hate housework. You make the bed, do the dishes and six months later you have to start all over again.")
3. Stop cooking. That's why take-out and microwaves were invented.
4. Minimize domestics. Buy enough underwear to last two weeks. Do laundry every other weekend. Alternate laundry weekends with grocery shopping. Stock up on cat food when shopping.
5. Take cat naps. A 2-3 hour nap will be enough to fuel you for several hours of writing. Take another nap before going to day job. Once a week have a lie-in and sleep for 12 hours straight.
