i need help finding my cat

my cat went missing on saturday around 2am in sutton in ashfield,around the carsic area. she wasn’t out long before my mum tried to call her in but every other of our cats came in besides her. the next day we weren’t really concerned but as times gone on she’s still not come home and now we’re very worried. we’ve spent two days outdoors searching for her, she’s never been one to stray far from our home as she’s skittish and gets spooked easily. sometimes when she is spooked she has slight seizures where her legs lock up and she struggles to walk but these only last for about two minutes and are very rare, she always comes back home when it happens so she can be around comfort. but it’s now tuesday and there’s been no sign of her anywhere. we have an abandoned building next to us and a forest just a bit up the street and we’ve mainly been searching around there as well as in areas where my cats tend to go, however we can’t get in the abandoned building as we’ll get done for trespassing there’s cameras everywhere. we’ve took treats with us constantly called her name and drove around the neighbourhood in the car calling for her to no avail. i’ve even got my other 4 cats to go in the abandoned building and try to search for her but nothing. i’ve posted on all of my social media’s and unfortunately no information has been provided to me and my family. i need help on what to to next, i will not give up on my baby until she’s found no matter what.

i’ve been searching with her sister neo 🐈‍⬛ this morning and neo was calling for her but there’s no sign of her anywhere. i’ve stuck her litter tray and a worn jumper with my scent outside and will be searching for her tonight when it’s late and quiet. she’s officially been registered missing through the vets and on animal search. i need tips on what else i can do to find her
