Milk Thistle Herbal Extract

I'm using this product for 2 cats. I like the fact that the dosage is so low--just 1/4 ml. b.i.d. The cat who is more laid back takes it without difficulty--followed by a treat. My other cat dislikes it, and sometimes ends up inadvertently getting it down her throat instead of in the side of her mouth. I tried putting it on a cat treat, but neither cat will take it that way. I think that's probably due to the taste and the smell of the alcohol in it.
