We are now up to 4 ball pythons and a red tail boa. Looking at building multiple enclosures on a shelf I am wondering would it be more cost efficient to buy them pre made? I like the AP cages. I am afraid that with that many melamine enclosures how heavy it will be plus room to add more if need be. If anybody has any pros and cons comparing both that would be very helpful. No trying to be cheap about this but also thinking that we will get more snakes in the future.
