I am in the process of building a 16'x24' shed. Half of it will be for my rats and half of it will be for my snakes. Of course it will be separated by a wall and both sides will be insulated.

My question is about ventilation for the rat room. I am wanting to put in some sort of window type fan for my fresh air intake. I also want to put in an exhaust fan of some sort, more than likely one that will go up and out the roof, was thinking the inline ducting fans, but I would love to see how others have their ventilation set up in the rat rooms (pictures with as much detail in writing as you would give.)

Also what brands of fans, both intake and exhaust, that are good.

And what, if anything, you would do differently about your set up. I am wanting this to last a while obviously.

Thank you for any input.
