How old should a kitten be before you can start cutting their claws. We have a new little kitten, he's a little over six weeks and his little claws are very sharp. We have been teaching him not to dig in but he's a kitten and full of energy, when he gets carried away he's destructive. We won't declaw him but just want to trim them when they get too sharp like we do with our older cat and wanted to know when it's a good time to start doing it and get him usd to it being done.
