PVC Ventilation?

Hey Guys,

So recently I have run into some financial issues and although I'm doing okay Im still working on digging myself out of debt. To combat my need to add more Ball Pythons to my collection, I retired my rack and set up my glass terrariums, and PVC enclosures that I had in storage. I figure if I have no where to put new snakes than I won't be out looking for them LoL.

Now to my question: These are the PVC enclosures I have set up.


This one is your standard two door PVC. I included a picture of the vents because I am concerned about air flow. I'm worried that this wont allow enough air to move through the enclosure which in turn will give my guys URIs.. Do you guys have any experience with this cage and have you noticed any respiratory issues with them. The guy at my local reptile store (I wont say which one out of... "respect") told me that I needed to cover the vents to allow for enough humidity in them. I asked him if its normal practice to cut off the source of oxygen to animals under his care.. I didn't get a response.. Lol

This is an example of my vision cages.. I like the design but I have never set them up yet so I can't comment on how good they are lol.

Thanks,

some times it is not the size of the opening but placement. A good vent placement will move lots of air poor placement does not. hi low vents often work well I would assume that the designer has figured out the best venting...
