My cat is 12 years old, big but not over weight. He always eats. Two days ago he lost his appatite and is now throwing up greenish bile. Dosn't seem to be in pain. What should I do for the vommiting and loss of appatite?? I gave him vasiline the last 24 hours just incase it was a hairball. Should I take him to the vet?
