Vomiting... I hate to but should I seek a 2nd opinion?
Much of his life, my cat has been a barfer. But lately it has gotten a lot worse. It started when he barfed a couple of times a day for a week. The vet looked and thought it was gastritis and did notice his mood was sour. He is usually super friendly and energetic at the vet. He prescribed famotadine and said to check back in a week. A week later he had a huge barf fest and the vet gave him some magic shots that made him feel better for a few days. He was kind of high or something. It was just cimetidine and an anti-convulsant or something. A week later he was really in bad shape, and vomited 6 times in a few hours. He could keep nothing down.
The vet gave him the same shots and, fearing dehydration might be causing severe constipation, he gave my cat an enema. Before doing any of that, he took x-rays and noticed inflammed intestines. He said it could be pancreatitis and we could test for it for something like $150 (they had to send the blood work away) and the test was not always successful or accurate. He gave me ranitidine and prednisone (former for acid, latter for inflammed bowels). He didn't think it was a food allergy because they are slow onset, and usually involve skin irritations first, unlike in humans.
That evening he had a lot of problems with his bowels, didn't eat, didn't drink, and was a shell of his former self. He sat still for hours on end. Any time he tried to eat or drink he would vomit. The vet said to keep an eye on him and report regularly on his status.
He didn't eat for almost 48 hours. The vet gave me k-pec which put him on the mend, seemingly. He ate immediately, kept his food down, and slowly improved. That was about 9 days ago. He's been a good trooper and taking his medicine as much as possible, I think.
Now he's back to barfing again when he eats. His mood, however, is great. I tried giving him k-pec again, and due to his reduced appetite squirted prednisone with some water in his mouth.
I'm becoming rather frustrated. I feel like there's a diagnosis that is missing. I love my vet but a month of this has been really tough to deal with. I have never considered a second opinion before, but now I am. Am I being too quick to judge? Is this sort of ailment common and hard to diagnose? Help?
