I haven't seen my beautiful cat for about 72 hours. He made himself scarce coz my father-in-law was visiting with his dog. But fil has gone now and cat no where to be seen. I have put notes with pictures of him through about 40 letter boxes and made some little posters to stick on lampposts. I've walked round the block rattling a box of cat biscuits. Is there anything else I can do? I'm so scared.
