I don't know if you can buy empty tiny seringes. I got mine from my vet. I do know that there is one that comes in the reptile first aid supplement that you can buy. Maybe your pet store sells it. Its made by Flukers and its called Repta-Aid critical care formula. Insectavore/carnivore emergency aid. This supplement comes with a mixing/measuring cup small seinge and a spoon. It will also help Rupert since its made for sick and malnurished reptiles and frogs. It is like $10.00 for the little kit but its worth it to save your little guy. Plus you can use the seringe to administer his vitamins and canned food. I know the stuff isn't cheap, but you may only have to buy it once. Rupert won't go through the whole can of that food. If it brings him back I think its worth it. I hope everything works out. I wish it was easier.
