My story: I went to look at a home over 10 years ago. Walked in (and my dog Sallie was with me) and I love the house. Great floor plan, just right for me & 3 of my children. Untill.... Sallie kept marking her territory in the house. The guy kwptr telling me "That's okay". He wasn't bothered at all. Needless to say I made one more attempt to see teh place at a "spur-of-the-moment" time and when the front door opened we couldn't go in.
Well anyway my friend convinced me to take the place The price was perfect) but I couldn't live it until I pulled all of the carpet out down to the concrete foundation, primed the concrete twice, treated it with some product for dog & cat, lay twice as much padding and lay new carpet through the entire house!
Pull up your carpet, prime and treat the foundation and lay something else other that carpet!!!
