I forgot to write the update on this forum. He was back to his normal self today and I still called the vet and they said it was only hair balls and to keep an eye on him and if he stops drinking or eating to bring him in. I might stop by there tomorrow to get a sample of some hair ball medication for him to see if that helps him. Today he was very loving. Every time he throws up the next day he just wants as much loving as you can dish out for him. But he is back to his old self again
