for the past three weeks, my 6 yr old spayed female cat will get up at 6am and walk around the house meowing for two hours straight. i will let her outside but she goes outside then she wants to come back in after ten minutes and begins her meowing again. when my mom tries to let her outside, she just pokes her head out and turns back around. she will stop if i come to her and walk with her but she just lets me follow her around the house then once i leave her and either go back to sleep or to another room, she begins her walk through the house once again meowing. i have no idea why she keeps on meowing because i never had any problem with my 15yr old spayed female cat doing this. she is driving everyone crazy in the mornings. what can i do?
