Our cat(castrated male) pees 3 -6 times a day. Three times a day in his litterbox seems to be the norm. I change his litter completely on Wednesdays, and then he immediately pees in the new litter (often while I'm carrying his litterbox back upstairs from the cellar - 13.5 lbs. of cat, jumbo litterbox, and litter - fun, fun!) . He goes for a walk every day on a leash, and if he has seen or smelled that another cat has been in his yard, he generally wets another 2 or 3 times.
