I have some damage at the seam in my bedroom doorway thanks to my cat. I need to fix it to get him to leave it alone. I thought I could just use those metal strips but the nails just go straight to the concrete and bend. Is there any other product I could use? Or something else that could be done (aside from replacing the carpet) to stop the unraveling and seal the seam to prevent further kitty damage? Thanks for any suggestions.
