I'm sorry to hear that your cat is barfing so much. I have a few cats that if they eat too fast then they will also barf. I don't free feed any more and I also feed them small amounts of wet and dry food. Sometimes if they drink a lot of water after eating then this will also cause them to barf. Sometimes it's also just due to hairballs so I try to give them some Petromalt hairball remedy at least once a week. I'd also get your cat checked out by a vet. It's also very important to take your cat in every year for an annual exam. I hope it's nothing serious. Good luck.
