Also good for rinsing your nose if you have breathing problems, I guess. Ideal for Luer lock syringes. However, it is so thin that it is easy for animals with sharp teeth to chew and swallow pieces. So be careful they don't swallow pieces bigger than they can get through and try not to let them bite into it, they might let them bite. A wedge to keep the mouth slightly open will help or shoot between the teeth. Either way, it's great for animals that refuse to drink as it's less aggressive than a hard spout.
