My mom and dad have been using all pine under the litter in Clover's
litter pan since they got her almost two months ago.  I asked around and
the people that i have talked to said that it was safe as it has been
kiln dried and it is not oily to the touch either.  Clover has had no ill
effects from this and I asked her original owner who i found out also
used it.  I personally don't use it yet, but am seriously considering it.
