There is not much I can do. I am only a dog and the lady has decided the cat is going to stay.
Each day Pilgrim creeps closer. The lady gives me plenty of treats when I don't lift a lip at the intruder.
The only thing I can do is eat the treats, and don't lift the lip and show my fearsome teeth so I can get even more treats. Sharing the house with Pilgrim does have it benefits!
