Teaching multiple biology classes on a tight budget? Let us help! This kit contains 50 jumbo grade Barn Owl pellets, Teachers Guide and 15 Bone Sorting Sheets. The pellets are whole specimens - not bits and pieces, heat treated and foil wrapped. These jumbo grade pellets are 2 in. and larger and can contain up to 6 prey remains. The pellets are packed in a sturdy 1 gallon bucket with lid for convenient storage between classes. Mountain Home Biological has been supplying pellets since 1994. All pellets are sorted, dried, heat treated and wrapped in our facility in White Salmon, Washington and monthly samples are submitted to an independent lab for testing. Soak pellet in water for 2-3 mintues prior to dissecting. Our pledge to you is complete satisfaction, from the time your order is received by our knowledgeable staff, to the arrival of your carefully prepared specimen.
