This packet is all about the imagination. It is a fully printable set of labels, exam notes and ID cards for your budding Vet Tech. It has kept my little's entertained for hours. It's helpful but not necessary to have a "medical kit" handy. Gauze, tongue depressors, band-aids, etc. I also use old bowls for "food" (usually made with pom poms or other appropriately sized items) Enjoy!!!
