You were a small mouse who was living on the streets without a hole or anyone to care for you. You lived in a city full of anthro-cat people, which is bad seeing as you are a mouse.
One day you awoke and saw a note next to you, it displayed an address on it at the bottom. The note read, "go there, its safer than on the streets." You decide that you have nothing else to do and head off to the address. Once you get there you see the house looming over you. It was quite small, pleasant and was painted green. You wondered how you would knock on this door until you realized that there was a ladder for mice to climb up and ring the door bell. Obviously this is a anthro-cats house, but maybe it was nice.
