Ace! That's what I was hoping you might see. I've noticed that sometimes when a cat's near remission giving insulin might bump numbers up a little and when the dose comes down (or if a cycle is skipped) the cat might start getting lower preshots.
Good that you're skipping tonight (I would!). Did you feed Nacho after doing the PMPS reading? If yes, it would be great if you could check his BG at the normal PM+1 and PM+2 times to see how his pancreas is handling BG levels round mealtimes unassisted. This would be really helpful in assessing whether Nacho might be ready for a remission trial (and yes, that's checking how BG goes without insulin and if a cat stays in normal numbers for 14 days the trial is considered a success).
Re ketones, you can get urine test strips at any pharmacy. Some helpful links:

Tips for collecting and testing urine
You can also get blood beta ketone meters (see primer). The strips ain't cheap, but you can test on demand in the same way as you'd test BG, with a blood droplet from the ear. Unless there were a problem, testing once a day is fine.
