When I still had my cat‡ making sure the dryer was closed after every load and empty before closed was something I got on my roommate’s ass about a lot
He had a hard time remembering it at first but after the first couple weeks he started remembering.
‡My cat passed away a few months ago at 18 years old. Not dryer related. He was as spry as a kitten until the last 3 months where everything went downhill fast. He passed away in July. I miss that little snuggle bug.
