Romeo has been taking NaturVet Quiet Moments Plus Melatonin. I included the ingredients label. His stool is little hard so was going give dose of Lactulose to him. Are these safe to use at the same time? Well same day. The Lactulose is from his vet for whenever he gets too hard stool. Thanks

As far as I'm aware, there are no interactions between ingredients, however if Romeo is experiencing constipation, I would let your vet know just to make sure it's still OK to give him the lactulose if it was originally prescribed for something else. Since melatonin can sometimes cause a bit of dehydration, making sure he's drinking enough water can also help with hard stool.
