Which part of the UK are you in?I have looked in loads of cat sitting websites but none so far cover my area. I am in the countryside!
Did he get some high carb food at +2.3? That may have prevented the drop to the 40s subsequently. You want to feed carbs and prevent a drop below 50. That way you can avoid a reduction and keep them on a good dose as long as possible.+2.3 51
(He was outside and didnt come back til now!
I would try the 3 drops rule for earning reductions. Get a +2 and +3 and feed high carbs if necessary. That will keep him safe for the 2.5 hours that you are gone. Let's see the AMPS.So you think I shouldn't go down a dose?
Tomorrow I have to be out from+3 to +5.5
Bit nervous about that at the same dose.......
