Occasionally, we cat-sit our daughter's cat. For travel to our home, she has to be given an anti-nausea pill 30 minutes before leaving. In spite of this, she travels unhappily, usually vomiting at least once. I used Easy Traveler for the first time yesterday, as we got her ready to go home after a 5-day visit. We put drops of it in her morning feed, and I spritzed her carrier inside and out. I was thrilled to hear she didn't vomit, was not upset, and had no problems during the drive. It works!
