Thanks, Sally. You were right, darn you! Any secret to your syringe method? I've only tried dripping, which took me about 10 minutes since I didn't know how much. I think I added more than the 20-30 drops I've read, but maybe it's because the cool carts were new. I guess I should trust you again and try a syringe, too. Why not? Anything more I should know about it?
Nothing to it! I ordered online from DrsFosterSmith (a pet store). They were recommended by someone on ECF. Very fast shipping! 18GA 1-1/2" needles .19 ea., 3CC Syringes at .15 ea.; 6CC Syringes at .35 ea.
Pop the little drip tip off the juice bottle, stick the needle in, and suck it up. LOL. There are precise measurements on the syringe. I use 1 ml....stick it down the side of the carto...all the way. Slowly inject. When
the filling is wet, it is done. If it gets a bit flooded, just suck some out(with the syringe). Then any extra, just shoot back in the bottle. FAST, easy and clean!
PS: The cartos are wonderful and even get their snap back.
