Helping a 5 Lined Skink - Advice - Cat attacked him

My evil cat caught a 5-lined skink. I've had experience rescuing them from the cats and never got to them in time and they died shortly after capture. Normally when I catch them they are already lethargic and barely move. This one, on the other hand, is crazy moving, obviously not THAT hurt, but still too hurt to be let go.

He has some skin ripped off on top, not deep, but still noticeable. He has a lot of skin torn off on bottom similar to the top, but also a deep wound around his gut area where you can see meat, however it isn't bleeding and I believe it is more of just a flesh wound (similar to scratching your own skin off to where it stings but doesn't bleed). Nothing is coming out of it, in a good way.

I've had him since 6 this morning (4 now) and he has already defecated in the bug box he is in, which I believe means his organs are alright. I have him in a medium size bug box with a paper towel lining the bottom that is well wet with water and some colloidal silver. (The colloidal is a natural antibiotic, I used it on a bullfrogs leg once when his leg had to be cut off after an almost fatal hit by a car. It healed in less than 4 days).

I'm curious what else I should do to help him. I have some fishing crickets and have tried to feed him but he won't eat, which I can understand, but I want to make sure he will make it. Thanks in advance!
