here's a few more options:
not knowing if you'll have to stay late... let alone not knowing whether you'll be an hour or two late... you could let it go until that day.
if you're only an hour late, chances are you'll be able to shoot at +13 and then at +11 the next morning given ruby's food spikes. her food spikes are higher than alex's! being able to do this is probably the only advantage in having a kitty who experiences huge food spikes! :mrgreen:
if it turns out you're 2 hours late, you could always shoot a token dose (like half the normal dose) just to get some insulin into her, but not enough to cause a problem shooting at +10 the next morning. it's not ideal, but stuff happens and we can't always stick to a 12/12 schedule. just know ahead of time the disruption will show up... maybe even a couple cycles later. however, you'll be able to get her back on track in no time. if you choose this option, i'd be sure to run home at lunch time on tuesday to get a mid-cycle spot check because of the *possibility* of the overlap giving a little extra oomph to that morning's dose. i'd also leave instructions for your dh to put some fresh food out for ruby mid-cycle to make sure she'll eat.
another option is to do an 18/18 schedule... which bring you right back on your current 12/12 schedule. again, expect the schedule change to throw her off for a few days, but it's not that big a deal. sometimes we just have to do the best we can with what we've got.
shooting an 18/18 schedule might be the way to go if ruby's range comes down lower than it's been between now and monday.
as the time gets closer, let us know what you decide so we can help.
edited to add:
for those reading...
these options are specifically for ruby. they reflect ruby's response to insulin... not that of other kitties. they may not be what's best and could cause a problem if used for YOUR cat.
