Question:

Should I make my cat NPO before vet appt for possible abdominal imaging?

Help, I’m really concerned about my cat, Luna. She’s been acting a bit off lately—sleeping more than usual and not eating her favorite treats. I’ve booked a vet appointment for tomorrow because I’m worried it might be something serious, and they mentioned possibly doing some imaging on her abdomen. The thing is, I’m not sure if I should stop feeding her before the appointment. Does anyone know if it’s better for her to be on an empty stomach just in case they need to run certain tests? I don’t want to do anything that might make the situation worse, but I also want to make sure any procedures go smoothly. Any advice from those who’ve gone through this would mean a lot!

Answer:

Thanks for the question! Preparing your cat for a veterinary appointment, especially if abdominal imaging like an ultrasound or x-rays is involved, is a good idea. For most imaging procedures, fasting your cat (making them NPO, or "nil per os," meaning nothing by mouth) can improve the quality of the images by reducing food and gas in the stomach or intestines.



For ultrasounds, fasting your cat for about 8-12 hours before the appointment is usually recommended. This fasting window helps provide clear images, as a full stomach can obstruct views of the abdominal organs. However, make sure they have access to water throughout this period; hydration is important for them.



For an x-ray, fasting isn’t always necessary unless your vet has specified otherwise. Alongside prep, observe your cat's overall condition. If you notice any symptoms like vomiting, diarrhea, lethargy, or signs of pain like vocalizations or unusual resting postures, these can signal more urgent issues that might require prompt attention.



Since every situation is unique, and to ensure your specific concerns are addressed appropriately, I recommend booking a video consult with Dial A Vet. This way, we can discuss the best prep for your cat's specific needs and any other care tips to make their visit as smooth as possible.

It was so easy, I needed some eye drops for my dog and thinking about going to the vet on a weekend made me nervous about the cost involved. Dial A Vet was a much simpler, cheaper option with faster results. Within 10 minutes of the call, I had the medicine I needed for my dog without an expensive consultation.

A great fast efficient service with a qualified vet who was lovely and helpful. Thank you Samantha. I was able to sort my dog at 6pm on a Sunday night for $49 - amazing. Highly recommend.

What an amazing service, at my wits end as I knew my beautiful dog had an ear infection, could not get into the vet for 4 days. Never knew there was vets online until I googled. Within 15 minutes on a Sunday I was taking to beautiful Samantha who diagnosed and treated our Jasper. Only $49. She trusted that we knew our boy and gave us lots of advice. I will definitely be using dial a vet every time and sharing with all my friends and family. Absolutely fantastic kind caring service. 11/10
