A veterinary IV catheter (also known as an IV cannula) is a sterile, single-use medical device inserted into a peripheral vein to establish intravenous access in dogs, cats and other small animals. Each box contains 50 individually blister-packed, sterilised catheters supplied in four colour-coded gauges 20G, 22G, 24G and 26G for fluid therapy, medication and anaesthesia delivery, and blood sampling in clinics, mobile practices and animal hospitals.
Key Benefits
- Reduced insertion trauma advanced, gently tapered catheter tip aligns smoothly with the needle bevel for a low-trauma, easy vein puncture.
- Radiopaque for safety 3 stripes of radiopaque line let clinicians confirm catheter position on X-ray.
- Painless, precise puncture siliconised, ground stainless steel needle with an ultra-sharp triple-facet bevel.
- Fast visual identification standard ISO colour coding (pink/blue/yellow/purple) speeds up gauge selection during time-pressured treatment.
- Sterile and hygienic individually packed in a rigid, easy-to-open blister for single-use veterinary infection control.

How to Choose the Right Gauge
Select the largest gauge (smallest number) the patient’s vein comfortably supports when rapid fluid delivery is needed, and a finer gauge for cats, kittens and patients with small or fragile veins. As a general guide: 20G suits medium large dogs, 22G suits adult cats and small–medium dogs, 24G suits cats, kittens and small-breed dogs, and 26G suits kittens, exotics and especially fragile veins.
Frequently Asked Questions
What gauge veterinary IV catheter should I use for a cat?
Most adult cats take a 22G or 24G IV catheter, while kittens and cats with fragile veins are often better suited to a 26G catheter for a lower-trauma puncture.
Are these veterinary IV catheters sterile and single-use?
Yes. Each catheter is sterilised and individually sealed in a rigid blister pack, and is intended for single use only.
What is the flow rate of a 22G veterinary IV catheter?
The 22G catheter in this range delivers a typical flow rate of approximately 36ml/min, suitable for adult cats and small–medium dogs.
Can this IV cannula be used on both dogs and cats?
Yes. The 20G–26G gauge range covers patients from large dogs down to kittens and small exotics, so the correct gauge can be matched to each patient’s vein size.
How many catheters come in one box?
Each box contains 50 individually packed, colour-coded catheters in a single selected gauge.
