Cats do get their nose out of joint when there is an interruption in their daily routine. They just do NOT like change, but get use to it in a short time after they check everything out.

I bet you got the cold shoulder when you let them out of the basement. I could almost here them saying, "HHHMMMMPPPPFFFFF, the NERVE of you."

Glad to hear that they have forgiven you and are back to their sweet selves.
