I never thought Tucker was abused or anything, I just think he was undersocialized and not exposed to many people. He probably got his way a lot based on how he reacts to discipline and being a brat when he doesn't get his way… He also, obviously, was lucky enough to have a stay at home mom for his previous 3.5 years which, I'm sure, lends to thinking he can pee whenever he wants.
To answer Christy's question, he has only peed once when I was home. He had let me know he wanted to go out by scratching on my door, but I was in the middle of something and was finished in about 5 minutes. In that 5 minutes, he had gone into the other room and peed on the sofa. I blamed myself since he did 'tell' me. It didn't happen again, but at the same time, he initially tried to run all over me and scratched every couple of hours to go out. In fear of another sofa soil, I would take him out but soon came to realize that he was pulling a fast one on me when he went out and just sniffed around and didn't pee or pooh. That stopped after about a week of taking him out and pretty much sitting in one spot until he peed and pooped, then not taking him out for at least 4-5 hours unless he ate a lot. I had to show him he wasn't in charge...
