Looking for info on the Freestyle Libre

I trying to find out any information on the Freestyle Libre for cats. I'm afraid it's the only way I'll be able to test Romeo. It would be very helpful to hear about anyone's experiences with it too.

Romeo is at the vet's right now. He stopped eating and I had to syringe feed him in order to give him his shot. He's started eating again at the vet's but his blood sugar level is all over the place and the vet is trying to figure out what insulin dosage he needs.
 
@Staci & Ivy is one user of the Libre. There's a mention of it here in another newbie's thread: https://www.felinediabetes.com/FDMB...ving-high-carb-food-4hrs.299083/#post-3253330
Hello, I’ve been using a Libre 3 on my cat, Ivy, for about 2 years and I’m very comfortable using them.
My cat doesn’t tolerate constant ear pricks, she gets very angry and will bite and scratch me.

I also test with a handheld meter when she hits “LO” readings on the Libre most especially.
There can be a discrepancy between when you see “LO” readings on the Libre and what the handheld glucometer reads.
I use a Contour Next human meter, but it could be any handheld human meter or a pet meter.
I install the sensors myself and I keep several on hand at all times because they can fail or be pulled off at any time by the cat. I don’t want to have to wait to have someone else put it on or be without data, or have to take Ivy to a vet for that to be done. (It’s one more stressor for you and your cat, plus additional costs).

It’s truly not that hard to put on. You just have to follow the directions very carefully. Once you’ve done it one or two times you will be very comfortable doing it.
I keep a “tube top” on Ivy, (previously had a T-shirt on her. She just didn’t like the T-shirt). But most cats tolerate a tee shirt quite well.
Your kitty may get used to wearing a Libre (and then you may not have to use a T-shirt, but then again you might always have to keep one on if he likes to pull the Libre off.)

For a Libre 3, I got Ivy her own less expensive, older phone that stays with her at home and I can monitor her 24/7, the data is sent directly to my own phone through the Libre Linkup App).
The phone does not require any active service, so you are not paying for an additional phone line. The phone operates on Bluetooth and uses Wi-Fi to send the data to your mobile phone so that you can monitor your cat’s sensor information at all times.
You can use an older phone model if you have one, or could purchase one used.
On the Abbott website there are lists of compatible, androids, or iPhones.

***I strongly recommend learning about how to use a Libre from the Facebook group:
“Freestyle Libre for Dogs and Cats”

They have so much valuable information, guides, tutorials videos, and everything you will need to learn about using a Freestyle Libre sensor and what supplies to use.

A vet’s office tends to use glue to install them, it is highly recommended not to use any glue.
The glue can flood and kill the sensor and it’s terrible on their fragile skin.

I hope this information helps and if you have any further questions, please feel free to ask :cat:
 
There can be big differences between the Libre BG and BG from an earstick and hand meter. Here is the lasted that I tabulated.
