Missing cat in Oceanway area

Hi all and merry chrysler. One of my parents cats got out today and hoping that anyone who may live in the area can be on lookout! His name is Mister. My parents live in one of the neighborhoods in front of First Coast High. We assume that he got out sometime this morning because when I woke up, I saw that the back door was open - around 10am. We didn’t notice until this evening until the hustle & bustle of the day was over when the cats usually come back out. We searched in a few neighborhoods along the road tonight but had no luck. He was a feral cat before he was adopted by my parents, but they’ve had him for about 3/4 years now, so we think he will hold his own, and hopefully come back when it’s time for breakfast. But if he’s spotted by someone I don’t know that he would come to you. Please if anyone sees him let me know. We really appreciate the help. Thank you!
