Well, in my experience, bunnies don’t normally enjoy being syringe fed. It’s VERY common for the CC to end up on the bunny, on your t-shirt, your face and your wall-paper during the course of syringe feeding. Pumpkin often helps though, they often love pumpkin. You can mix the med with pumpkin too if she likes pumpkin.
This is sth that requires some practice and a huge amount of DETERMINATION. Like Roberta here said to her bunny Pascal when he had to be syringe fed: You will eat this even if it kills me.
There is a space between the front teeth and the back teeth where there are no teeth so clenching is no use. Find that space and take care to deliver the CC (or med) slowly, so she swallows and don’t get the CC into her lungs. You may have to make the CC-sludge rather runny. And try to get some in her if not all.
Patience, firmness and practice and it will get easier. Last fall I had to syringe feed my bunny Yohio for a whole month. It was very difficult at first.
edit: Both Roberta’s Pascal and my Yohio were fine eventually.
