Kat,

How often to you clip your cat's nails? That is what happens when they aren't trimmed. No, you're not a bad mother. Sometimes a nail can be overlooked (like the dew claw) and it will grow into the pad. You did the right thing in clipping and removing it and treating the pad. I inspect my cats claws every week just to make sure. And I am religious about clipping them every 2 weeks.
