Can you let me in please?

I went round to my brother's house this afternoon to pop some birthday cards through his letterbox - there are 4 family birthdays this week. Knew they would all be out at work but their cat Felix came over to greet me. He obviously wanted to be inside but I couldn't oblige. Sorry Felix. He is a grand old gentleman - about 17 years old now. Half Siamese and half ???? He is deaf but apart from that he seems in good health. Nice surprise to see him today.
