My cat (1.5 year-old Bengal) has been vomiting (once a day) sine 3 days ago, and she makes this painful noise before she vomits, and it sounds like she in a lot of pain. I took her to the vet on Thursday and the vet ran blood test and found really nothing (except that he red cell count was higher than normal). He said she's probably having a stomach problem and gave her medication for it. I've been giving her the medicine since then, but she's been vomiting every morning and still making the painful sound. She just did it twice already early this morning, and I'm starting to really worry about this painful noise she makes before vomiting. My vet's closed now and I'm waiting till they open at 10AM, but I'm not sure if I'll be able to bring her in today and I'm wondering if anybody ever had a similar problem and know what might be going on... Could this be some kind of intestinal infection?
