What should I consider when choosing the best cat tracker for my cat?

Choosing a tracker for your cat is one thing; making sure your choice is the best is another. 

According to experienced cat mums and dads on Reddit, here are five important factors to consider when choosing the best cat GPS tracker:

• Accuracy
• Range 
• Battery
• Comfort
• Price

Let’s talk about each of them.

1. Accuracy 

Many cats are adventurous, and when given the opportunity, these cute creatures love to explore. During the course of their adventure, they are highly prone to getting lost or exploring areas that could be dangerous to them. 

Having a cat GPS tracker with 99-100% accuracy is important because it keeps you in the loop of where your cat is, where they’ve been, and where they are headed. 

According to Meowden, a good GPS tracker should show you the exact spot your cat is on the map, and the margin of error should be no less than 20 meters. 

2. Range 

If you have an escape artist or a very adventurous cat like my Sunshine, the best cat GPS tracker to get must have a wide range. A tracker with limited range might fail when your cat roams far, and this makes monitoring very difficult. 

A GPS with a wide and solid range, like Tractive, can help to keep you updated about your cat’s whereabouts even when they are miles away from home. 

3. Battery 

According to Grepow, the type of battery used in a pet GPS tracker can significantly impact its overall performance. 

A GPS tracker might have all the features needed to track a lost cat, but when it has a weak battery, it’s worthless. If you’re using GPS with a weak battery, dump it.

You don’t want to spend 5 hours searching for your cat in the wrong direction just because the tracker battery died two hours ago. A GPS tracker with a weak battery shuts you out at unexpected times, and that can be dangerous for your cat. 

Prioritize getting a cat GPS tracker with a battery that can last for at least a week or more for your cats.  

4. Comfort

While you want to provide utmost security for your cute cat, you don’t want to do that at the expense of your cutie’s comfort. 

A smaller, lightweight tracker is generally more comfortable than a big and heavy GPS tracker. Also, big or heavy trackers can lead to soreness of your cat’s neck or choking.

5. Price

Be sure to investigate properly and uncover charges like activation fees, data traffic charges, platform access fees, and more. 

Find out about any subscription fees to avoid unpleasant surprises later in the future. Some trackers might be affordable at first glance, but they have hidden charges that might be above your budget. 

However, while seeking cost-effective trackers, do not do so at the expense of performance. Be sure to weigh the performance and price to get the best cat GPS tracker for your cat.

Honorary mentions 

This section includes amazing cat GPS trackers that didn’t make the main list. This does not cancel them out totally, as they still have the important features of a cat tracker. 

They are:

• Byte tag
• Cat Tailer
• Kippy

1. Byte Tag 

It comes with a QR code that contains your contact information. This way, when your cat goes missing, someone can scan the code and contact you. Despite the innovative QR code feature, ByteTag doesn’t have a GPS or Bluetooth feature that allows you to track your cats. You just have to hope the right people come across your cat and contact you. 

2. Cat Tailer.

Cat Tailer is a lightweight tracker weighing about 17g, and this makes it a great pick for cats who do not like to have things hanging on their neck. Cat Tailer has a limited range, and it’s mostly suitable for indoor cats or cats playing in the yard. 

3. Kippy

If you want to be associated with a community of pet lovers, Kippy has the right app for you. The tag comes with an app that includes a community of cat owners sharing their adventurous experiences. Apart from community, the app shows your cat’s activity status, alerts you when it breaches geofences, and helps you live track your cats. 

What are the steps to follow to choose the best tracker for my cat?

From going through multiple online rabbit holes, here are the three steps you need to follow to choose the best tracker for your cat.

1. Identify your tracking needs

The first step to take when considering a cat GPS tracker is to identify your tracking needs. To identify the correct tracking needs, ask yourself these questions:

• Is my cat an indoor or outdoor cat?
• What exact features do I need?
• Do I want a GPS tracker, Bluetooth tracker, or a mobile tracker? 

2. Research size and colour 

Is your cat the type that doesn’t like things hanging on its neck? Is your cat sensitive to certain colours? Knowing the answers to this question will help you pick the most suitable tracker for your cat. 

3. Determine your budget 

Your budget should determine the type of cat GPS tracker you should go for. If you’re on a very tight budget, avoid subscription-based trackers because it might be difficult to keep up the payments. Instead, go for trackers with zero subscriptions.
