Missing 2 year old cat. Female, black & yellow eyes. Goes by the name Sooty. Friendly, family cat

Our family cat went missing on Saturday 14th February 2015 during the evening. She has now been missing for over 48 hours. She goes out during the daytime but she always comes home. This isn't her typical behaviour. She is a black, two year old female cat with yellow eyes. We have been searching the area but have had no such luck at finding her. She goes by the name Sooty and is a family cat. We are getting quite worried now as I like I said this isn't her typical behaviour. 
If anyone has any information on her whereabouts please contact me through email, message or call.
