Channeling my mother

Ask anyone who knew my mother and one of the first things they would say about is she loved to home repair/home decorating/gardening. If you called her on any given day, she probably could be found painting/staining/installing/planting something. I have already determined that I did not inherit my mother's artistic gene, however, it seems I've been blessed (and depending on who you talk to, including my husband, that might be stretching it) with the "fixer-upper" gene. Over the last 2 weeks, I've embarked on more "fixer-upper" projects than I have in the past 2 years. It all started with me finding 4 rolls of contact paper in my mother's things. I immediately thought of my kitchen and the nasty old paper that was in there, along with the shelves that had nothing and were merely nasty themselves. Over the course of about 6 hours, I put contact paper on almost every shelf in my kitchen & pantry. And then proceeded to rearrange said shelves.
My new project is somewhat ambitious, and my husband has already expressed doubt that I will get it done. When we moved in, it seems that the previous owners had a cat, that was allowed to use the carpet in the main bathroom as a litter box. First of all, putting carpet in a bathroom seems like an extremely idiotic idea in the first place, but I digress. It smelled....BAAAAAAAAD. Poor Emma wouldn't even brush her teeth in there & the smell hit you as soon as you walked in the front door. It was awful. I got lots of advice on how to get rid of it, but they all required that the bathroom be well aerated. Which it isn't, as it doesn't have a window or good air flow. So spraying anything on there that required we allow it do dry was not going to happen.
We have a birthday party here this Saturday and I didn't want to have to make all the guest use the 1/2 bath by the back door. So, I decided to rip up all the carpet, padding & anything else that was under there, and put new flooring down. It already smells better and I haven't even put anything on the subfloor yet. The people who put this carpet in were morons. They put carpet over linoleum because they were too lazy to rip up the old flooring. So now I have a decision to make: be an equal moron and just put new vinyl flooring over the old stuff, or bust my hump & try to rip out the old stuff that's probably been there for 25 years. Did I mention we're having a party here Saturday? There is this product called Kilz that is a sealant of some sort that I was told would block out the smell of cat pee that soaked into the subfloor (which is most certainly likely). I think it's time to go visit our friendly neighborhood experts at Ye Olde Home Depot. It's times like these that I wish my mom were here so I could call her & ask her advice. But, all I have now is WWMD (What would Mom do).
