Cat miaowing at night

[edsheeranpaidmoretaxthanccola]

Our cat who is around 11 (she was a stray) has started miaowing inconsolably at night. When we go to her she doesn't want food, water or cuddles. Only at night. Does anyone have any ideas? Our next stop is the vet but I thought I'd try here first

Mine does this sometimes
Vet first definitely, Ive had a bit of success with aktivait https://www.petdrugsonline.co.uk/aktivait-for-ageing-cats as meowing at night can be a sign of dementia

Thank you, Yes Queen we'll definately take her to the vet but at least there's some hope with the medication. Thanks for replying
