So long story short, cat has scratched up wallpaper in the hallway. I want to remove the wallpaper, plaster and paint it as I’m less likely to get problems with the cat damaging the wallpaper again. My mum doesn’t allow me to do it, stating that it is just one wall that is damaged and it’s a really nice wallpaper. She’s literally making a HUGE deal about it and is making me feel guilty and actually putting me off doing it. It is my owned property that I paid for. She only comes to visit to see her grandkids. But she’s making it her whole business calling me “mental” for changing the wall because of the cat scratching it. I don’t know what I’m looking for here, other than to ask if she is being unreasonable? Do I take down the wallpaper and paint the walls or not?
