>>how big should they be? I am building my first rack system and need to know how big the holes in my adult sized tubs (used for rat snakes) should be. I've heard that if they are to big the snakes will rub their noses raw trying to get out.

>>Thanks

I prefer drilling holes with a stepped drill bit, starting at about 1/8" and working up to about 3/16". The bit I use is titanium coated and hasn't cracked a single Sterilite tub even cold tubs.

I drill all my holes the same size and over ventilate and cover up un-needed holes, easier to cover up than drill more.

Cheers
