She's doing really great for two skipped doses in a row... personally I would not give any more than .25 if you feel like you need to give something, but there is also the "drop" option a lot of people like when they're doing really great but you want to give something.
Again, some cats just need a diet change and she has only recently done that, also some cats run higher naturally and never need insulin so she's doing amazing.
Annnd I see you went with the .25 lol sorry I didn't reply quicker.
It's a solid choice and now you'll know how she does, if it causes lower numbers than you like or a bounce.
And yet it's not too much so it shouldn't keep you up all night.
