Crazy Cats

I just got back into my home after spending 40 minutes in a t-shirt and boxers in damp 50 degree weather with gusty winds, not very chilly but a bit nippy and I'm getting over a cold. I stepped outside for just a moment to secure some deck chairs..when I finished with the chairs and turned around to come back in and I hear "click" and there is my cat Loki (shown in my avatar) standing on his hind legs with his head slanted to the side, pawing at the storm door latch...he always gets agitated if I don't carry him outside with me and apparently he has discovered how to get even.

I ended up having to break the handle/latch to get back inside..guess I'll be making a trip to the hardware store tomorrow.
