Hermes just turned 1 on Monday and today when I woke up there was a bunch of cat vomit on the floor and I have 5 cats so I had to figure out who was throwing up but as soon as Hermes ate he threw up.

He has thrown up now 4 times today and it's after he eats.

Any advice would be greatly appreciated. I'm going to take him to the vets tomorrow hopefully I can get in.
