My cat Cha Cha has been throwing up, cant seem to keep food down. The vet took xrays and found now obstructions, did blood work and found nothing wrong, urine sample was good. She gave him fluid injection for dehydration and cerenia for nausea. He was ok for a couple of days. This morning he vomited his breakfast and last night he vomited a small amount of clear spit. I got the care credit to pay for this to help me stretch out the payment. Anyone have something like this happen, what is it!

If it is an obstruction, he will probably need surgery
I would go back to the vet and demand they find out what is wrong for once and for all!
