Vet‑written answer
<p>You're doing the right thing by asking this question — it definitely sounds concerning. When a cat is experiencing symptoms like vomiting bile and not eating or drinking, it’s vital to get to the bottom of what's going on. Each diagnostic tool has its strengths, so let’s look at your options.<br><br><br><br>A **barium x-ray** involves your cat swallowing a contrast dye that makes the gastrointestinal tract more visible on x-rays. This can help identify blockages but is more time-consuming and sometimes stressful for cats.<br><br><br><br>An **ultrasound** provides a more detailed image of the internal organs without requiring sedation. It’s particularly good for identifying soft tissue issues and can be very effective in spotting obstructions in the intestines.<br><br><br><br>A **scope (endoscopy)** is more invasive but allows for direct visualization and potentially removing the obstruction, depending on its location. However, it usually requires anesthesia and isn't as broadly available as an ultrasound.<br><br><br><br>Given the symptoms you describe, an **ultrasound** is a safe and effective next step due to its non-invasive nature and immediate results. However, personal factors and your veterinarian’s expertise can make a difference.<br><br><br><br>Watch for signs of dehydration, lethargy, or persistent vomiting, as these may indicate a serious issue. If your cat's condition continues to worsen, I strongly suggest booking a video consult with Dial A Vet to evaluate the situation and guide you on the best course of action.</p>
