So, for now, we're shuffling the food back and forth between him and the fridge several times a day until he eats it. Thankfully, he doesn't seem to have a problem with the refrigerated food. The eventual goal is to get him to eat two meals a day, one dry, one wet, but we figure since he's a little thin and under the weather now, it's better to just get him to eat, and deal with schedules later. Personally, I wouldn't mind going with all canned, but M thinks that's a little much money wise.
In the interest of disclosure, the dry stuff is felidae, and the wet is innova chicken something flavor, in the large cans. We picked them out of lists recommended online, because a) that's what the store in town sold, and b) they were cheaper than some of the other options that looked pretty comparable. Not much to say on the dry stuff, but the wet does not smell nearly as terrible as I was expecting. Essentially like the canned chicken you buy for yourself. This makes the larger (and thus cheaper and less wasteful packaging-wise) cans much more reasonable, since it doesn't stink up the fridge unreasonably. I'm not fully sold on the fact that it contains apple and carrots and other non-catty things, so we may experiment with other brands later too.
