I applied minoxidil (or Rogain) to the top of my head about five to five and a half hours ago and went to bed. My cat decided to get my attention this morning my pawing the top of my head in the exact same spot. It’s been hours and the area is completely dry, but I don’t know how toxic this stuff is. I know it’s poisonous to cats. Am I overthinking this or will she need to go to the vet?
