Best Glucose Meter for Cats: Our Top Picks

Diabetes in cats is becoming more and more common. When it comes to testing your cat’s glucose levels, sometimes cat owners choose to use regular human blood glucose meters instead of one specifically designed for a cat. The downside is that the meter is not properly calibrated for a cat and can result in a false reading.

This is where a blood glucose meter for cats comes into play. The meter is specifically calibrated to the blood concentration in cats to help give the most accurate reading possible.

To help you find the best glucose meter for cats, I’ve listed a few of the best options. At the end of the article, I’ll also go over a few tips as well as some frequently asked questions about cats and diabetes.

What to Look for in Blood Glucose Meters for Cats

As you look over the blood glucose meter products we’ve listed below, there are a few features you’ll want to pay attention to specifically. I’ve put together a quick list for you to reference as you shop. The best blood glucose meter should combine these features for the best overall experience.

Ease of Use

The best glucose meters for cats are those that make it easy to both draw blood as well as obtain accurate results. We’ll talk more about accuracy in a minute, but having an easy-to-use glucose meter for cats can make a huge difference in your (and your cat’s) overall experience.

The best glucose meter for cats works with you as you try to test your cat’s blood sugar levels. It only takes a few moments with a cat to learn that they don’t particularly like to be held down and pricked. Who would be? But the ability to not only require a small blood sample but also operate in a straightforward manner can make for the best glucose meter for cats.


The accuracy of a blood glucose test is imperative when it comes to your feline friend. After all, you may need to introduce measures to regulate your cat’s blood sugar levels, so relying on the results to be accurate is a huge deal.

Lancing device

Lancets are the small needles required to obtain a blood sample to test. The lancet must retrieve enough blood to place a small blood drop on the testing strip, but that doesn’t mean it has to be a painful experience.

Many of the best glucose meters for cats include a lancing device that can be adjusted for various depths. Since you are testing for blood within the cat’s delicate ear, you’ll want to have this adjustability to make the experience as pleasant as possible for your feline friend.

While the lancing device doesn’t typically change much from one glucose meter to the next, a proper lancing device takes a blood sample in the safest and cleanest way possible.

Cost of Test Strips

Investing in a glucose meter to test your cat’s blood sugar is one thing, but having to purchase a supply of replacement strips can often be a larger investment altogether. These testing strips can be unique to that particular glucose meter, which may or may not affect their pricing.

Testing strips are also not something you can replace easily, at least when it comes to substituting a lower-cost product. Glucose meters are typically calibrated specifically to certain testing strips, and changing the replacement strips could affect the accuracy of that particular glucose meter.

The Alphatrak2 glucose system is probably one of the best glucose meters for cats on the market. The numbers are both accurate and easy to read with this blood glucose meter. There are instructions included in the box that shows you how to use the meter. 

You can reach out to AlphaTRAK with any questions or concerns regarding their product. You can also find instructional videos on the internet on how to calibrate the meter, how to get a sample, and how to get a reading.

There are many positive reviews regarding this product. Many people have commented on how fast and accurate the readings are from this glucose meter.  Many owners have stated that only a small amount of blood is needed to get an accurate reading in seconds, which is especially useful for cats. After all, it isn’t always easy to keep your cat calm and under control.

One complaint most owners have about this glucose meter for cats is that the test strips are expensive. The kit does come with 25 test strips, but most people have found the test strips for this kit are more expensive than other test strips for other kits. All in all, this is still rated as one of the best glucose meters for cats on the market and will not disappoint.

Here is a very helpful video I found showing how to use the Alphatrak2 glucose meter for your cat.

How to Tell if Your Cat is Diabetic

If you’re not sure whether or not your cat is diabetic, here are a few symptoms you can keep an eye out for if you notice your cat’s behavior has recently changed. I also recommend seeking out veterinary guidance if you have pressing concerns.

Loss of Weight

A cat with diabetes cannot process and break down glucose properly, which in turn deprives their cells of the needed nutrition. To make up for this lack of nutrition, the body will break down fat and muscle tissue in order to get the nutrients needed. This can reduce your cat’s weight in an unhealthy way.

Change of Litter Box Routine

Diabetes causes excessive thirst. Your cat will most likely be making more bathroom trips due to the increased water intake to compensate for being thirsty. Another thing to look at is where they are going to the bathroom. A sick cat will most likely be defecating outside the litter box or not covering its bowel movements with litter. These are big signs of an illness or poor health.

Appetite Changes

Many cats will stop eating if they do not feel good, while others may eat everything in sight. This will vary from cat to cat. It is possible for a cat to experience both of these symptoms at the same time, which can really cause some erratic behaviors. This is due to the body trying to adjust to the inability to process glucose and extract nutrients properly.


Vomiting due to diabetes is a sign of waste build-up in the body. This happens when your body starts to break down fat for energy due to lack of nutrients from food.

Unsteady Gait

Diabetes can also affect the way your cat walks or moves. It affects the nervous system of your cat, which can lead to unsteadiness or odd walking.

Your Cat Looks Ill

Your cat will generally look sick. A formerly bright and healthy coat may look dull and lifeless. Your cat’s eyes may also be dull and not as bright as they used to be. Your cat will also struggle to fight off other minor infections and illnesses. They may be slow to respond or seem sluggish as well.

How to Collect and Test a Blood Sample from Your Cat

It’s a good idea to keep a log of all the tests you do on your cat to share with your vet at a later time. Here’s a quick reference guide on how to test your cat’s blood glucose level.

  1. Once you have a glucose meter and glucose test strips, you are ready to collect and test a sample from your cat. Make sure you lay the kit out with everything you need within reach. Much like with a human glucometer, you’ll need to obtain some blood from your cat. The best place to collect the blood is from your cat’s ear flap, which is also called the pinna.
  2. Before trying to collect a blood sample, make sure that your cat’s pinna is warm. Simply hold it gently between your hands for about a minute or two. Warming up the pinna helps circulate more blood to the area, which will make collection easier.
  3. Quickly take the lancet and quickly prick your cat’s ear. Make sure the area you prick is a hairless part of the ear. Always make sure to use a new lancet and never an old one. The last thing you need is to give your cat a skin infection from a dirty needle.
  4. Once you see a small drop of blood appear, collect it on the test strip. After you have collected the blood, make sure to gently apply clean cotton or a gauze onto your cat’s ear to help reduce and stop the bleeding. 
  5. Insert the test strip into the glucose meter as instructed. Once the reading appears on the screen, compare it to the normal level for cats. Note the reading and contact your local vet if the glucose levels are highly irregular.

Who should purchase a blood glucose meter?

Purchasing a glucose meter for your cat can save you a lot of money in the long run. Let’s face it, trips to the vet for your cat are not cheap. Being able to monitor your cat’s glucose levels from home will save you money and put you in control of your cat’s health. Being proactive is the best way to keep your cat healthy. If you feel confident and responsible enough to monitor your cat’s blood sugar, then this is the right purchase for you.

If you feel that you will forget to test your cat, or simply cannot do it, then the best bet is to continue taking your cat to the vet for monitoring. Letting blood glucose get out of hand can be very dangerous and potentially fatal if not properly monitored.

What are the differences between a human glucose meter and a cat glucose meter?

While it might seem tempting to invest in a human glucose meter instead of one for cats, there are a lot of differences between the two glucose meters that could affect not only your results but the actions you take based on those results.

For instance, the blood sample required for a human glucose meter is much more than is necessary for a cat glucose meter. After all, most cats are relatively small compared to the average human, so the ratio of blood required adjusts accordingly.

Cat glucose meters are also calibrated specifically for feline diabetes. A human glucometer may technically monitor some of the same markers, but in order to get the most accurate readings, you’ll want to invest in the proper glucose meter.

How do I calibrate my cat’s glucose meter?

Cat glucose meters come with a control solution you can use to calibrate your glucometer. This solution should be applied to test strips at least once a month in order to make sure your cat’s glucometer is reading accurately.

Most manufacturers will list a control solution range on the bottle of the control solution or on the test strips box. As long as the control solution reads in this range, your cat glucose meter should be calibrated properly.

What should my cat’s glucose level be?

The normal level of glucose in the blood is 80-120 milligrams per deciliter or mg/dL. After a large or high-calorie meal, it may rise up to 250-300 mg/dL. If your cat has diabetes, the blood glucose level can rise to above 400 mg/dL.

In fact, it is not uncommon for some diabetic cats to have glucose levels as high as 700-800 mg/dl. More commonly, they will be in the range of 400-600 mg/dL.

How does anemia affect my cat’s blood glucose levels?

If your cat is anemic, this can affect the results of testing their blood sugar. For example, in order to return accurate results, glucose meter manufacturers determine a general hematocrit level, which denotes the number of red blood cells in the blood.

If your cat is anemic, the number of red blood cells in the blood can be different than this general level. This could cause the test strips to read inaccurately.

Final Thoughts

Diabetes in cats is a serious health condition. When purchasing the best glucose meter for cats, you want to look out for its accuracy. If you have an accurate reading, you will be able to properly monitor your cat’s blood glucose levels without any expensive trips to a vet.
