I recently placed a cache using a ziplock container that is about 5"x5"x2" deep but I wouldn't recommend it for an area with animals. It was big enough for a full sized pencil and pad though. Another option is some of the small rubbermaid or tupperware containers I've seen at Wally World. The small drink containers seem to be about the size of a pint can except they are see through and have a screw top. You would just need to glue the straw closed and use a small pencil.
