He is 8 years old. He hasn't eaten since Tuesday (4 days ago). He threw everything up and is now dry heaving. He drinks very little water, only to throw that up too. I tried to give him pet grass--threw it up. I forced some caster out with a dropper last evening to see if he had a hair ball blockage. That stayed down. But nothing passed. What could be the problem? I have been giving him water with the dropper too.
