If you cat stays indoors, it likely own’t wear down its nails naturally through walking and clawing trees outside. You can give your cat scratching posts but ultimately you might decide to trim your cat’s nails periodically to keep it from clawing up your furniture too badly.
Surprisingly, some cats don’t mind if you hold them and trim their nails. Other cats may require the “burrito method” where you wrap the cat in a towel or blanket, pin it down, and then trim its claws. Make sure you do it quickly before your cat uses those untrimmed claws to draw blood and rip your skin off.
