Dawwwww… who’s a widdle cutie? Who’s a widdle Sicky? You are!
Re: the wet/dry food controversy: I split the difference, and give 'em dry kibble in the morning (they free-feed on that) and a can of wet food in the evening. Glad he’s getting more energetic and boisterous – that’s gotta mean he’s feeling better!
Melts into a baby talking puddle. What a cutiepatootie he is! Sick kittens don’t play, so he must be feeling great. He’s going to grow up to be a fabulous cat.
BTW, I didn’t mean that I thought that anyone but you were thinking this was too bloggy for this forum. Besides, you just asked for more opinions 
So don’t bother asking for a forum change unless you really want to.
Now to the wet food vs dry food thing, according to me:
(I’m not including cites, but if you want them for anything, ask and you shall receive.)
Cats are obligate carnivores. The perfect food for a cat is a mouse. They might eat a little grain that was in the mouse’s belly, and they might sometimes eat some grass, but cats truly evolved to eat an Adkins diet. Lots of protein, limited carbs.
Even the best kibble is about 40% grain so it can hold its shape. Cats aren’t evolved to eat that much grain, so it makes them fat AND they poop a lot more. Grain fed cats fart and there is nothing worse than cat farts.
Cats also evolved in a desert. They got most of their moisture from their food. Cats who eat mostly kibble are in a constant state of dehydration. That’s not good for their kidneys, livers and other organs that require constant flushing.
Now to the “kibble cleans teeth” thing. Cat teeth are basically the same as human teeth, they are just shaped differently. Their teeth are shaped so they can rip meat, they don’t chew as much as break their food up into pieces that they can swallow.
Even if they did chew their kibble, because of the shape of their teeth the grain (which makes kibble stick together) will stick to their teeth because of their eating habits.
Consider this…do your teeth feel cleaner after you’ve eaten a piece of toast?
I don’t like to get cat bites. I try to avoid it whenever possible, but if given my choice, I’d rather be bitten by a feral cat than a kibble fed house cat. The feral will bite harder and really mean it, but the bites will be clean. A bite from a house cat is sure to get infected really fast.
I can give you cites for everything but the getting bitten part. That’s totally subjective and only my experience and hearsay from other cat rescue people.
So…aren’t you sorry you asked? 
Anyhow, thanks again for saving that lil cutiepatootie. How big is he now? He looks to be about 1 1/2 K?
