We went camping this weekend, and I saw a kitten scrounging around the campground. It was a little gray tuxedo, maybe about 4 months old. When I saw it I thought of you and this little gray sweetie.

I approached the kitten and it immediately ran. It was coming out in the daytime and looked a little dirty, so I think it's a stray, but it is quickly turning into a feral because I couldn't even get close to it. So I couldn't help this little gray kitten, but you can help your little gray kitten. I say take her, and deal with your grandmother, parents, whatever later. Even if the kitten is locked in your room she's better off than being on the street.

Or, at the very least do like Phred says and build a little house on the back porch and encourage her to stay there instead of crossing the street.

Poor little kitty.
