I crochet cat toys and use organic cat nip that is double rolled in stocking material. I make sure all my toys are safe for all kitties. I hand stitch back to make sure there are no big holes for kitties to pull stuffing out. All toys can be "refreshed" by putting them into a zip lock plastic bag....which makes the catnip like new.
I try to make new patterns regularly, so please keep checking back for new pieces.
