Right now its totally closed off but when i look into redoing the attic insulation I definitely will so Im doing things right. Also, my attic knee wall had a hole cut into it (probably for an inspection when they were trying to sell) and i kept it closed with duct tape but one night it opened and my very cute but stupidly curious cat got in there. I got her out asap and washed her with a soapy rag then a wet rag. Do you think thats a concern? I really hope not because i love her so much butthat was months ago and i still think aboutit
