arunefx yours is better but can you change the picture of a cat for a fox? the cat in your picture doesn't look bothered by the fireworks going off at all! The cat flap looks a bit too big on that wall. Can you put it into a door instead? Also the cat inside looks a bit out of place. Perhaps a cat curled up asleep would be better so it looks more relaxed.
Ok we are getting good ones now. Please get remaining entries in within 48 hours maximum as I will be deciding the winner.
the punisher i think yours is best - just need to make the cat flap look more realistic in the door. i could do that by taking a photo of the cat flap from a slightly different angle.
crowquill i also like your cartoon style one above. let me check with my colleagues and find out which we will go for.
Arunefx I'm please to announce yours is the winning design! Thank you so much for all the entries. It's been an excellent contest. It was very hard to choose the winner in the end.
