I cant say I have ever pee'd on my cloth seats in my '12 Premium, but many here have complained about the way the cloth wears in these cars. I can attest that it does not appear to be as rugged and durable as the cloth in my '06 Forester, but so far, with 10,000 miles on the odometer in 6 months, I have no issues. However, I do not have kids. I Scotchguarded the heck out of all the cloth surfaces on the interior, including the rear cargo area, headliner, carpets and seats, and have had a few spills of coffee, and a buddy of mine got guacamole all over one of my seats recently on a road trip, and i was able to wipe it out with a washcloth and water, but again, I Scotchguarded them the day after I bought the car, then did it last week right before the road trip. With that said, if I had kids, and they had a habit of peeing all over everything, grinding their feet into the seats, etc, I may go the route of neoprene seat covers. If you're not keen to the idea of a seat cover I'd do leather over bare factory cloth.
