Under normal circumstances, it is NOT necessary to stay up and feed a cat every couple of hours. That was a special occasion last night... what we lovingly call a PJ party. Most of us feed several small meals throughout the day. Some do 4 times per day, some do 6 times per day. Much of that is what works for your schedule. I do 6 feedings per day with a meal at each shot time and then 2 small snacks in between during each 12 hour period. If you can get one non-food influenced reading and one that is food influenced during the day today, that should indicate if Barry is holding good low numbers or still needs insulin. I'm sure you want to be able to get a good night's sleep tonight so if I were you, if he does need to go back on some insulin (fingers crossed he doesn't), I'd start fresh tomorrow morning. It's clear if he does need more insulin, the dose needs to be reduced! And in his case, I'd probably reduce more than our normal reduction amounts. Let's see what the readings are today and then we can help you decide next steps.
