How long will the woman be gone?

W   Min-soo, I’ll be going out of town for business next week. I was wondering if you could watch my cat for the seven days that I’m gone.
M    Your cat? I didn’t know you had one. Sorry, but I’m actually allergic to cats.
W   Yeah, he stays inside most of the time. Well, do you know anyone who could watch him? I asked my brother, and he can’t do it either.
M    Why don’t you put him in a kennel or boarding house? I don’t think it would be too expensive to put your cat there for a week. But first, I’ll try calling my little sister. I think she likes cats.
