Do you own or rent your place? Does your place have a garage or shed for storage? Do you have basic hand tools?
Can all of your snakes be moved into one room that can be closed off from the rest of the house?
Are your snakes consolidated in racks or do you have tanks all over the living room?
Does your house have decent, well-insulated double-pane windows or do they leak like sieves?
Are you looking for a solution to cover you during the winter, or also for when the power is out?
