That picture reminded me of what happened with my friend's cat. She (the cat) loved to play with plastic bags, pounced on them, got in them, etc, etc. One day though, she managed to get her head through the handle hole and got scared. My friend told me she was running through the house like a wild thing and she thought it was funny at first and was laughing at the cat. Then, she realized the cat was truly terrified and was trying to get away from the bag. She said it took her forever to catch the cat and by the time she did, they were both so out of breath with their hearts racing that she thought they one or both of them was going to have a heart attack (early 70s lady, 13 year old cat). She won't let the cat have a bag to play with anymore.
