Awesome! You guys are great - thanks so much for the welcomes and information! This seems like a wonderful site; I'm glad I stumbled across it

I've spent the weekend reading and reading, so I feel like I'm getting a good education, but there's always stuff that comes up that requires the knowledge of folks who have btdt.
I saw a vet tech for today's appointment and I wasn't thrilled. She was very adamant that I should be feeding Hill's W/D or M/D rather than the FF or Friskies. She also was sure there was no issue with doing the second dose at +8 hrs. I didn't think it would be, so asked to clarify and she assured me it was fine.
Oh, btw, Phobos isn't eating as much as he should (which I still haven't figured out how much that is), and when he does eat it's only a bit at each sitting. Is this going to be a problem with the insulin? Like, I can only get him to eat 1/8-1/4 of a (5.5 oz) can at one time, and usually not when I want him to. The vet tech today said it's not a problem, but the vet on Friday said he really needed to eat 1/2 a can before the insulin shot. How does one figure out how much food a cat should be eating in a day? The vet on Friday said he should be eating 1 can/day. The tech today said 378 cal. at his current weight, which would be 2 1/2 - 3 cans for the w/d & m/d. And the cat food cans say 1 oz. food/ lb of cat weight, which would be almost 14 oz. Sorry, I'm new to using canned foods.
Phobos was given the a/d on Friday because it is higher calorie and he was barely eating. I'm weaning him off of it, though, as he seems to be eating more. I knew it was higher carb than we want, but didn't think it was really high so I figured it would be okay for awhile.
