My cat Salem is throwing up once or twice every day. At first I didn't think anything of it, but he wouldn't stop. I took him to the vet and he got vitamin shots, a blood test, but the results came back fine. Sometimes he will stop for a few days then start again. The vet told me to put him on hills prescription diet and he has been eating that food ever since, but he is still throwing up. I am getting really concerned about him and I don't know what is wrong, any help would be great, thanks.
