Common questions and answers
What Is a Sonogram?
A sonogram is a test that uses sound waves to take pictures of what’s inside your cat’s body. It helps the vet see your cat’s organs without surgery.
Sonograms are often used to check:
-
The kidneys, liver, or stomach
-
The bladder and urinary system
-
The heart (called an echocardiogram)
Can My Cat Drink Water Before a Sonogram?
Yes, most of the time, it is safe for your cat to drink water before the test.
Drinking water can even help in some types of sonograms—especially when the vet needs to see the bladder clearly. A full bladder gives a better view.
But it’s always best to follow your vet’s advice, as they may give you different instructions depending on the reason for the sonogram.
Can My Cat Eat Before a Sonogram?
In most cases, you should stop giving food 8 to 12 hours before the test.
Why? Because:
-
Food in the stomach can block the view of other organs
-
It may cause gas, which makes the images blurry
-
If your cat will get sedation, an empty stomach is safer
Step-by-Step: How to Prepare Your Cat for a Sonogram
-
Talk to your vet – Ask if your cat should fast or avoid water.
-
Stop food – Usually 8 to 12 hours before the test.
-
Allow water – Unless the vet says otherwise.
-
Keep your cat indoors – So they don’t eat or drink without you knowing.
-
Bring comfort items – A blanket or favorite toy can help your cat feel safe.
-
Arrive early – To complete any forms or pre-checks.
-
Follow vet instructions after the test – Especially if your cat got medicine to sleep.
Tips from Vets
-
Water is okay, unless the vet says not to
-
Do not feed treats or snacks before the test
-
Tell the vet about any health problems
-
If your cat is nervous, ask if calming medicine is needed
Special Case: Heart Ultrasounds (Echocardiograms)
For heart ultrasounds, food and water rules may be different. If your cat is only having a heart check, drinking water is usually allowed and fasting may not be needed. But always double-check with your vet.
Frequently Asked Questions (FAQs)
Q: Can my cat drink water the morning of the ultrasound?
A: Yes, unless your vet says no. Drinking water may even help, especially for bladder scans.
Q: Why does my cat need to stop eating before the test?

Q: Will my cat be shaved for the sonogram?

Q: Does a sonogram hurt my cat?
A: No, it’s painless. Most cats stay calm, but some may need a little medicine to relax.

A: It usually takes 20 to 30 minutes. If your cat is very nervous, it might take a bit longer.
When to Call the Vet
If you’re not sure about food or water rules, or if your cat seems sick or scared before the appointment, call your vet right away. It’s better to ask than to guess.
