Kris - this board is invaluable to me. Our vets don't use Lantus in their practice so I had nowhere to go for help. Back before 2000, I first found this board when I had another diabetic boy (the beef/pork based insulin was discontinued and everyone had to change). My boy amazingly lived for over 8 yrs after diagnosis through that transition - it was very difficult and this board was a great help. PS Teasel looks just like my youngest Munchkin.
