[catwoman]

how long has this been going on? How frequently are you giving him the medicine? Maybe you could try gradually switching his food. The reason I say this is because maybe he has a food allergy. maybe the food is causing him to throwup. Also if it is going on for a long time, I would call the vet. He may have a blockage of hair??? Keep grooming him daily and contact your vet. It's really not good for cats to be constantly throwing up. Please let me know what happens.
