i would think the pee would kill the grass...
St. Augustine is particularly urine hardy. Any grass will do, but you will replace the flats more often on other types. My son had a pug/corgi mix and they lived in an apartment and that is what they did for her and it worked great. They installed a sliding glass door doggy door on the slider going out to the balcony. Those install without hurting the door or frame, so worked well for the rental. They lived there a year and a half and never had to replace any of the flats.
Take care,
