The reason why you would not want to just add one drop of GSE to your pets food is, because this is not enough for most animals. right now your cats are babies, and one drop may work out for you, but in the future, more drops may be needed more frequently throughout the day. I am not so sure cats will like the taste of 4 or more drops of GSE in their food 4 times a day. When you are finished adding the desired amount of GSE to the gel capsules, rub a little olive oil on to it; administer it to the animal. When you insert the capsule in the animals mouth, make sure it is inserted to one side of the throat. Then close the animals mouth for just a few seconds. After this, feed the animal a nice juicy treat.
