The Great Escape

Okay...so they can sue me for the copyright infringement. They won't get anything out of me. I could change it to "The Great Jail Break", but this is cat paradise, not jail. Anyway, we were moving skylights on Thursday so the garage door was open. We opened the screen door to the garage to get some air movement and let the cats enjoy it. The crazy kitten, so far only known by the moniker of "brat", decided to climb the screen. We chased him down and went to the garage at the end of the driveway. By the time we returned, we saw 2 cats near the deck. Doug questioned whether they were neighborhood cats but had a dreadful feeling that ours had escaped somehow. I took Gabriel with me and captured a kitty while Doug found the escape hatch and blocked it off. The brat had punched his way through the screen door. I grabbed a cat and brought it to Doug. We went for the other one, who really was kind of freaked out. I don't blame him. The dog kennel is close to the deck, and he was being subjected to harassment. I'm happy that they are all back safe and sound. The current dilemma is what to do with the screen door so that we can use it again. How do you cat-proof it?
