My retirement plan is to befriend an eccentric elderly person of means with a beloved, much pampered cat that will inherit their entire estate, and take on the job of live-in caregiver to that cat. Perfectly happy to braise a steak and cut it intricately into bite-sized pieces three to five times a day if I get my own swimming pool.
As it is, I just cat-sit for normal cats that eat the food of the proletariat.
