Do you cut gerbils nails

You can trim a gerbils nails with a pair of baby fingernail clippers, very very carefully looking to make sure you do not trim too much off and get the pink inside part of the nail (the quick) if you cut too short it will be painfull and bleed. Even regular adult fingernail clippers will do as long as you are careful. Also watch that you do not get the other toes in the blade or a very tramatic amputation could happen and possible death from bloodloss.

You don't have to. They will dig in something and that will trim the a little. You can hirt them if you clip their nail in the wrong spot.
