Ginger male cat missing in Canton, Cardiff

Missing - last seen in Canton, Cardiff on Saturday night (28th March 2015). Please help us find Bogart. He's 4 years old, very friendly but nervous around some people. He's a home cat and only goes out 1-2 hours a time so for him to be away for as long as he has so far, is concerning for us. Sadly, he has no collar on (he always takes them off as soon as we give it to him). Please contact me if you have any leads. Thank you. 07968476241
