the cat got shut into a bedroom accidentally and she has scratched the pile off the cheap nasty carpet at the side of the wall. Fraying black nylon mesh on view for about an inch wide and 3 long. Six month inspection due in may. Can I patch it myself? Sure I've had carpets before with bits joined together with, like gaffa tape underneath. Or get a carpet fitter to try? Or leave in full view and accept that I may be asked to repair or replace entire carpet (gulp)
