White cat missing from Dublin 22

Hi everyone🌷 Toyash is 4 years old, male, chipped and neutered. He is missing from Old Tower Crescent, Clondalkin, Dublin (near Liffey Valley) since 25/03/2022. He was wearing a red flea collar and has different eye colors brown and blue. He never did this before and he is afraid of strangers. I'm really worried about him for more than 3 weeks. Please contact me if you know anything!🙏
