Crappiepappy, Oral Syringe is what I used, just couldn't think of the proper description. I used 6mm which I think describes the tube size as all the tips appear to be the same. The Smelly Jelly seems more fluid than the nibbles and I don't think will harden over time. I'll take the syringe out of the fridge and see how it is after a month or two. Thanks for the input. Pop
