My cat loves your catnip.   I have one question however.  I'm finding very
small, hard dark brown items underneath the cardboard of her scratcher, and
that's where I usually sprinkle the catnip.

They look like seeds of some sort, but I'm not sure.  Upon very close
inspection, each little hard item has what appears to be two white dots on
one side.  At first, I thought it could be a carpet mite, but my vet put it
under a microscope and couldn't determine what it was.  I've also seen them
in the container of catnip.

There are perhaps 1/32" large (maybe smaller.
Would anyone happen to know what these are?
