I am building a tortoise "barn". it is for sulcatas. The two that I have are currently using a house with a 2 foot wide opening. They are both about 80 lbs. I expect them to be around 90 to 100 lbs at the end of next year. I am wondering what size opening that I should use. I want it to be big enough so that I don't need to enlarge it later. What height and width do you recommend? I will use plastic stripping that is used in warehouses. it has worked well for me on their current 4 foot x 6 foot house. I also have a door to seal it when temperatures are to low. Thank you for any assistance that you can give me.
