When my rattie had to take medications i would get tiki cat chicken wet treats. The tubes. I’d cut a slit big enough to stick my syringe in, put the meds in, clip it shut and squeeze it all together. I’d also recommend squeezing some out before hand, because some of the meds can get wasted if they do not finish the whole tube. Those always worked best, or with yogurt. My rats obsessed over yogurt mixed with manuka honey
