Too much Insulin?

[Julie & steve j]

I'd welcome some advice please. My cat has been diabetic for 3.5 years. This past 18 months he has been on Lantus (glargine). His glucose numbers have been consistently high (20+) for most of the day, however, the vet hasn't been concerned as he has been maintaining good body weight. This last few weeks however his weight has started to drop. The vet has done a urine test, blood MOT and a fructosamine test. The urine and blood test have not found anything significant and his fructosamine test has come down from over 400 to 380. My concern is that he may be on too much insulin and bouncing. This was found once before when a frutosamine test showed that he needed an increase in insulin (his glucose was around 450) but a freestyle libre fitted after the fructosamine test showed he was in fact dropping very low and then bouncing which resulted in a reduction in insulin. It also happened at the same time of year when the weather warmed up. Has anyone come across this before where one test shows an increase needed (fructosamine) and another shows too much insulin (libre) and does anyone know if warm weather can make a difference to glucose levels? I'm very tempted to get another libre fitted but the vet I'm with currently hasn't been too successful with the applications and isn't keen to use them. Any advice would be appreciated.

If your vet will prescribe the sensor, maybe try putting it on yourself? I was initially afraid to do it but I applied my first one and it is still on over a week later. If it is something you're interested in, there are a lot of good tips on this forum and on Facebook.
As far as your other questions, I really am not sure. I'm sure someone more experienced will come along and help.

Thank you for your advice, appreciate it. I hadn't thought about applying a sensor myself. I'll look into it.

How much insulin are you giving at the moment?
I would strongly advise you to test before giving the the insulin so see it is safe to do so.
Also there are no tests in the pm cycle at all and that is when cats often drop lower.

For applying the sensor yourself I recommend you join the FB Libre for dogs and cats group.
https://www.facebook.com/groups/2894089194158745
It is a closed group so you have to ask to join the group. They respond fast to request to join.
To place the Libre yourself you need a clippers to shave the spot where it goes.

Many thanks for taking the time out to reply to my question. Benny is currently on 3.5 IU of Lantus twice daily. Unfortunately I'm unable to get too many readings during the week however, the readings I have obtained are very mixed. Some have been low (less than 10) and others around early twenties. The reason I was thinking of trying the libre again was to establish if Benny is dropping low. I'm also seeing some days that he is eating very little food during the day but more overnight, possibly due to the warm weather?? It may be a combination of things which is causing Benny to lose some weight but I want to consider all possibilities with his diabetes before I get further tests/scans with the Vet.
