I had to give my girl something similar when she was a very poorly 4 week old stray, when I first found her. I'm afraid that I have a no nonsense attitude when it comes to medication. I put it on my finger and wiped it inside her mouth. I do the same with tablets as well - straight in the mouth. I can't think of another way for you to give it, unless you can squeeze it into a pippet and give it that way?
