a loud stern NO, and pick them up and take them outside, even if they are in the middle of the act they can finich outside, NOT in the house. as for happys problem I have no idea what to do, I have NEVER cought her in the act and there is no way to keep her out of the basment, the carpets have been shampooed several times to remove the smell of old accidents, but its not working, she responds to no scolding after the fact, because I have no idea how long ago it was that she did it.. drives me insane, its like she is afraid to come upstairs to be let out, either that or she is just to lazy

edited because knowing people her the term "tossed" will be taken litterally.
