To begin with, have patience. If the cat is new, scared or spooked, it may take a while before the cat feels ready to come out. Try placing food out for the cat at a likely exit point, to encourage the cat to come out. If the cat knows the sound of its favorite food being shaken, especially treats, try shaking them near the exit point. Keep noisy/boisterous animals and children away from the exit and general area where the cat is hiding, to avoid spooking it even further. Or, use catnip or toys if you know the cat loves them. Sometimes it can help to sit nearby and talk soothingly to the cat, to reassure it that you’re there and that it is safe to come out. Other times, it’s just best to give the cat space to allow it to come out when it’s ready. This may be nighttime, so be ready to let the cat inside if it’s hiding outdoors.
