Firstly, I have to say that I was coming home anyway, and your letter didn't make a bit of difference. I am a cat and I will do as I please, as is my feline way.
Please do not think, however, that I am not aware that you are thinking of selling up and leaving the rat race to go and live on a narrow boat. As you well know, boats do not suit cats. You had better stick to your promise that you will not leave until I give sign or signal that it is ok. And please do not think that you will be able to hasten my departure.
PS What about a pouch of catfood in the morning as well as the evening?
