Ultrasound is one of the most valuable diagnostic tools for cats, who are notoriously good at hiding illness. It provides real-time images of internal organs, detects tumors, checks organ function, and guides biopsies — all without the radiation of X-rays. For cats, ultrasound is often preferred over CT or MRI due to lower cost and no general anesthesia requirement.
The average cost of a cat ultrasound is $450, with most owners paying between $300 and $800 depending on the scan type.
Cat Ultrasound Cost by Type
| Scan Type | Cost Range | Average | What It Evaluates |
|---|---|---|---|
| Abdominal ultrasound (complete) | $300–$600 | $450 | All abdominal organs — liver, kidneys, spleen, bladder, intestines |
| Cardiac ultrasound (echocardiogram) | $400–$800 | $600 | Heart structure and function — by cardiologist |
| Pregnancy ultrasound | $250–$450 | $350 | Confirm pregnancy, check fetal viability (after day 25) |
| FAST scan (trauma) | $200–$350 | $275 | Quick check for internal bleeding or fluid |
| Bladder ultrasound (focused) | $200–$350 | $275 | Check for bladder stones, crystals, tumors |
| Ultrasound-guided FNA (biopsy) | $350–$600 | $475 | Ultrasound-guided needle aspiration of organs or masses |
| Eye ultrasound (ocular) | $250–$450 | $350 | Eye conditions when retina can't be examined visually |

What Cat Ultrasound Detects
- Kidney disease: Chronic kidney disease (common in older cats), kidney stones, kidney tumors
- Hyperthyroidism: Thyroid gland enlargement
- Bladder stones and FLUTD: Crystals, stones, bladder wall thickening
- Intestinal disease: IBD, lymphoma, intestinal wall thickening
- Liver disease: Hepatic lipidosis (fatty liver), portosystemic shunts, liver tumors
- Pancreatitis: Pancreatic inflammation — common in cats
- Cancer: Abdominal masses, organ enlargement, metastasis
- Heart disease: HCM (hypertrophic cardiomyopathy) — the most common cat heart disease
- Pregnancy: Confirm pregnancy and fetal health
Frequently Asked Questions
How much does a cat ultrasound cost?
A cat ultrasound costs $300 to $800, with an average of $450. Abdominal ultrasound costs $300–$600. Cardiac ultrasound (echocardiogram) costs $400–$800. Pregnancy ultrasound costs $250–$450. Total including exam, scan, and interpretation is $475–$1,115 for abdominal ultrasound.
Does pet insurance cover cat ultrasound?
Yes, most pet insurance covers ultrasound when medically necessary — for diagnosing illness, cancer staging, heart disease evaluation, or kidney disease monitoring. Reimbursement is 70–90% after your deductible. Routine pregnancy ultrasound may not be covered.
Does my cat need sedation for an ultrasound?
Usually no. Most cats tolerate ultrasound well with gentle restraint. The vet shaves a small area on the abdomen and applies warm gel. Some anxious cats may need light sedation ($40–$100). Cardiac ultrasounds typically don't require sedation either.
What's the most common reason cats need an ultrasound?
The most common reason is evaluating chronic kidney disease (extremely common in older cats) and investigating weight loss, vomiting, or changes in appetite. Cats hide illness well, so ultrasound often detects problems before they're clinically obvious. Other common reasons: heart murmur evaluation (echocardiogram for HCM), pancreatitis, and suspected cancer.
