i was fretting because i had let them scratch in the pine shavings litter a few times between putting paper towels down.  then i thought they would need some grit to process any shavings they might have swallowed.  now i'm reading that the calcium can kill their kidneys.  i have given them a little bit since yesterday & none today. 
is it too late - have i hurt or killed my babies?
