Her nails may need to be trimmed more frequently (every few weeks) if she cannot use the scratching post as much as she used to. Trim her nails to just above the quick—the blood vessel that runs up the middle of her nail. Cat’s nails tend to curve under towards the foot pad when they grow too long, which would be...
