I walk past an apartment house every day, and often see a cinnamon-pointed Siamese sitting in the window of a second-floor apartment. Today she was sitting on the outer sill of the open window. Since these people are renting, they might not be allowed to put cat nets on their windows. I have a piece of transparent net that would be big enough to cover the window she was in today, and which wouldn't be noticeable from the street. Do you think it would be weird for me to knock and ask the people if they'd like to have it? I feel funny doing it (I don't know how I'd react if a perfect stranger did it to me), but I'm really afraid the cat will fall. The last time I saw a cat doing that, I photocopied some information on cat nets and stuck it in the people's mailbox.
