Wow, if she's only peeing 7 times in 24 hours that isn't bad. I have all mine trained to pee pads(the newest one hasn't learned to go to them yet, so, she's still using the floor..
), but, the ones that are trained pee more than that in a day. When they're trained to pee pads, they learn they don't have to hold it, so, mine are constantly using the pads. It would be a good idea to have her checked, but, it doesn't sound like she's going all that much....
