Any advice at all would be helpful. My cat was totally fine then suddenly started throwing up through night. Took him to the vet that morning. An X-ray was done and showed some fluid in his belly which I was told was normal because of the vomiting and he was dehydrated. Next, an ultrasound was done and nothing, no masses no tumors no blockage of any kind. It was obvious my cat is in pain. Lastly, a blood test which came back with an elevated level of calcium at 12 and from that, she diagnosed him with stomach cancer or cancer that is localized to his stomach or digestive track, even though everything else was normal. He was given a steroid shot and we were sent home with steroid pills. I just find it so hard to believe this diagnoses being that everything else came back normal including no masses of any sort. It’s only been one day now and the steroid shot doesn’t seem to be working. He’s very weak which is unusual for him because he’s normally an active, some what hyper boy, he seems to be in pain and is barely eating. He only gets up to drink but then vomits a lot a few hours after. He hasn’t moved his bowels but is urinating in his litter box... no blood in vomit or urine. He’s only 9 years old. We were told by the vet to take him home, see if the steroid injection helps to make him comfortable for the time being and if it doesn’t work then we will need to make that decision, the decision I can’t even think about without crying. I honestly don’t know what to do at this point. I tried calling the vet today to get some of my questions answered but I never received a call back. Has anyone else had a similar experience? Part of me thinks maybe the vet is wrong but I’m not sure if I’m just giving myself false hope. Any advice or suggestions will be greatly appreciated.
