My 13 month old boys, Max & Milo have been house-trained to pee pads and doing very well until a week ago. Now they are peeing anywhere and pooing under my kitchen table. I am going crazy trying to watch their every move.

Any ideas on why this is happening? I have reverted back to rewarding them every time I catch them going in the RIGHT spot hoping that will help. Could this have anything to do with them not being
fixed yet? I have noticed in the last month or so they are playing more aggressively together.
