Danny has been missing from his home in the Milton of Campsie area since Sunday, May 1.
The all black male cat is four-years-old, neutered and chipped.
He was not wearing a collar when he went missing and has been described as a friendly but timid boy so may be wary of approaching people.
Please check all sheds, garages and other outbuildings you may have in case he has become trapped.
If found, (Danny is pictured on the right!) please get in touch with Missing Cats in Scotland on 07456 586 853.
