Yes this is what happens when Lou goes crazy and decides he wants to jump on and play with the cat. As you can image Tiger-lily who is ten does not appreciate this behaviour, and hisses and swipes at him. This sends Lucifer into a crazy barking maniac, and he is put outside.
Usually there is some barking and hissing exchanged through the glass, but after a minute or two Lou goes into sulking mode. He will sitting staring at the cat with his bring brown eyes pleading to get let back in.
The funny thing is the cat is the only one of us he’ll listen to. She is his favourite. Tiger still remembers our old quiet beagle who was her best friend, so hasn’t fully adjusted to a crazy young beagle. She loves Lou even when he goes crazy, she just doesn’t trust him yet. And who could blame her.
