Arthur tends to have a little bit of an attitude. Once again, he was on the dog bed. Trail wasn't sure that he should be.
When staring at him didn't make him move, Trail moved in to physically remove him.
After a little bit of tussling, Trail found something else to do and along came Bill. He enjoys the dog bed and was determined to lay there even with a cat.
Later, once again, Arthur had the bed all to himself.
All this does is reinforce Arthur's opinion that cats do indeed rule.
The dogs totally disagree and besides, the cats are outnumbered!
