Lost cat, Ecru Court, 2, Gosnells - female, fluffy black with slight brown colouring

She’s a fluffy black cat with slight brown colouring. She has big greenish yellow eyes. She’s on the medium size. She didn’t come home for dinner on Monday night, which she has done before but after 2 nights it became alarming. Have been calling for her at night and during the day. Not like her to just disappear as she’s been an inside cat consistently for at least 4 years. She’s not wearing a collar for that reason too.
