Hi. According to kitten-rescue.com, you can add 2 drops of vegetable oil to a kitten's food. This is their recommendation for kittens who are still being bottle fed, so I would think it would be OK to add a couple of drops to your kitten's food. This site even says a little dab (about the size of a match head) of Laxatone can be given. However, it does go on to say that if the kitten does not pass a stool in 48 hours, to take them to a vet. You could always call your vet and see what they think about this, just in case they have a better idea.
