Poor kitty. If Bleu is throwing up consistently (more than 2 times within a 24 hr period), then yes this is cause for concern that he may be ill and in need of medical attention. Also if he is lethargic and unwilling to eat, or throwing up water, then those are also causes for concern. A vet visit is needed to do necessary testing to find out what the underlying problem is so that he gets proper treatment.

However, if he only had one or two bouts of vomiting, is otherwise acting normal, and has a good appetite, then I would recommend fasting him (no food, only water) for the next 12 hrs so that you don't continue to upset his stomach. Then after that offer him small amounts of a bland diet (tuna and white rice) for the next few days, then slowly transition him back to his normal diet. He may have just eaten something that upset his stomach or may even have an irritating hairball. I hope that this helps and I am hopeful that Bleu feels better soon. Best wishes and take care.
