Whether you’re monitoring anaesthetised veterinary patients, managing hypertension, or running nurse clinics, the CAT+ Doppler offers a practical, cost-effective solution built around real clinical needs.
The CAT+ Doppler is one of the UK’s most widely-used veterinary blood pressure monitors, trusted by first-opinion vets, referral centres, and universities for its accuracy, reliability and ease of use. Designed specifically for small animals, the CAT+ provides clear Doppler sound, dependable readings and long-term durability, all in a compact kit that gives your team everything they need straight out of the box.
Veterinary teams choose the CAT+ because it consistently performs where cheaper or generic systems fall short. Unlike standard human Dopplers or fragile probes, the CAT+ is engineered for the realities of daily practice, repeated cleaning, regular handling, and the need for fast, accurate results.
The CAT+ features a flat Doppler probe that sits securely against the limb or tail, making placement quicker and more stable than alternative smaller probes.
This design reduces slipping, improves reading accuracy, and makes it easier for both experienced clinicians and newer team members to obtain consistent results.
Veterinary equipment must survive daily handling, cleaning, and the occasional accidental drop. The CAT+ probe is notoriously tough, designed to withstand the knocks, bumps and general wear that occur in a clinical environment.
Where fragile Doppler probes may fail or require frequent replacement, the CAT+ gives years of reliable use, helping practices reduce long-term costs and avoid interruptions to clinical work.
Accuracy is the core reason vets invest in a Doppler system. The CAT+ delivers consistent, repeatable readings, even in challenging patients such as cats, rabbits and small dogs where oscillometric machines may struggle.
The clear Doppler sound lets clinicians confidently detect systolic blood pressure (and sometimes diastolic), essential during anaesthesia and for hypertension monitoring.
The CAT+ arrives as a complete veterinary blood pressure kit, supplied with the essential accessories needed for immediate clinical use. From cuffs and sphygmomanometer to gel, headphones and carry case, everything is included so your team can begin monitoring straight away.
The kit is designed for uninterrupted day-to-day use, with our recommended rechargeable batteries and charger included as standard to ensure the unit is always ready when needed. Every component has been selected for clinical reliability, giving practices a professional, ready-to-use setup without the need to source additional equipment.
When choosing a BP device, clinicians often compare the CAT+ with generic or human devices. While these may appear cheaper, they are rarely designed for the harsh realities of veterinary use, often lacking suitable cuffs, stable probe positioning, and the durability required for routine clinical work. Over time, this can lead to inconsistent results and a shorter working lifespan, unlike the CAT+, which has been specifically designed with these challenges in mind.
The CAT+ is widely regarded as a gold-standard Doppler because it allows clinicians to hear the arterial signal directly, providing immediate feedback and control during measurement. This is particularly valuable in animals, where movement, anxiety, and pulse quality can vary significantly between patients – situations that oscillometric devices can struggle to interpret reliably. In these cases, the CAT+ allows the user to adapt in real time based on what they can hear, rather than relying solely on an automated reading.
For many practices, the CAT+ remains a dependable choice because it performs consistently in real-world conditions and continues to deliver reliable results over years of daily use.

The CAT+ Doppler uses the auscultatory method to determine systolic blood pressure, a technique that underpins the validation of all regulated blood pressure monitoring devices. To achieve FDA, CE and UKCA approval, automated and oscillometric systems must demonstrate accuracy when compared against this reference method.
Because the CAT+ allows the clinician to directly hear the arterial signal, it provides clear, repeatable systolic readings without relying on algorithmic interpretation. For this reason, some organisations even use the CAT+ as a reference standard when assessing or validating other blood pressure devices.
The CAT+ arrives as a complete clinical kit, including cuffs, sphygmomanometer, gel, probe, and carry case. It is ready to use straight out of the box with no extra accessories required.
The CAT+ Doppler is ideal for:
Any clinic that requires robust, repeatable blood pressure measurements will benefit from the CAT+’s reliability and ease of use.
The CAT+ Doppler fits seamlessly into a range of clinical workflows:
Safe Anaesthesia Monitoring: During surgery, maintaining blood pressure is critical. The CAT+ provides fast, reliable systolic readings that allow vet teams to adjust fluids, anaesthetic depth and cardiovascular support with confidence.
Hypertension Clinics: Cats, especially seniors and those with CKD, are increasingly diagnosed with hypertension. The CAT+ helps practices deliver clearer diagnoses, track treatment progress and build long-term patient care plans.
Nurse Consults & Preventative Care: Because the device is easy to use and quick to set up, nurses can run blood pressure clinics autonomously, improving practice efficiency and enabling more proactive monitoring.
We provide ongoing support for CAT+ Doppler users, from setup guidance to replacement cuffs and accessories. Our team is experienced in veterinary blood pressure management and can assist with everything from product selection to troubleshooting and maintenance.
This ensures your investment remains reliable long-term and that your team feels confident using the device across different clinical scenarios.
The CAT+ Doppler is most commonly used for blood pressure monitoring in cats, rabbits, and dogs, particularly in patients where reliable systolic readings are essential.
In addition to blood pressure measurement, the CAT+ is widely used for pulse detection and assessment of pulse quality across a very broad range of species. Because it relies on direct Doppler signal detection rather than species-specific algorithms, it can be used on virtually any animal with a detectable pulse, from small exotics to large mammals.
The CAT+ Doppler and oscillometric monitors approach blood pressure measurement differently. While oscillometric devices rely on automated signal analysis, the CAT+ provides direct audible feedback, giving the user greater control over probe placement and cuff handling during measurement.
Many practices value having both options available, using Doppler measurement where direct feedback is helpful and automated monitoring where workflow or patient compliance allows.
We provide ongoing customer support, setup guidance, and access to replacement parts and consumables. Our team is experienced with veterinary monitoring equipment and can assist with any questions or technical needs.
Even experienced veterinary teams can fall into habits that compromise blood pressure reading accuracy. This guide identifies five common mistakes and provides practical solutions to help your practice obtain reliable, consistent measurements every time.
Despite the name, the CAT+ Doppler is a multi-species blood pressure monitor trusted by veterinary practices worldwide. Find out which animals you can use it with and why it performs so well beyond feline patients.
A new peer-reviewed study published in the Journal of Feline Medicine and Surgery has compared the AutoCAT+ oscillometric monitor with the CAT+ Doppler for systolic blood pressure measurement in cats. Across 131 paired readings, the two methods produced closely matched results, offering encouraging clinical evidence for practices considering automated blood pressure monitoring.
Obtaining reliable blood pressure readings in cats can be challenging, but success lies in the details. This guide covers essential cuff selection principles and patient preparation techniques to help your practice achieve consistent, accurate results every time.
Thames Medical has supplied veterinary practices for over 30 years, with a focus on reliable, well-supported clinical equipment. The CAT+ Doppler remains one of our most trusted and requested products because it consistently delivers what veterinary teams need: accuracy, durability, and ease of use.
