I don't know why my cat does this, but i will often wake up as early as 12:30 a.m. to my 3 and a half year old calico bawling to go out side. the most recent was last night. is this behavior unnatural? and why does she do it? this has been happening off and on since... i want to say maybe january. i will be starting high school next year and i study under a program that has very complex study requirements. i can't waking up in the middle of the night like during school. Is there any way to prevent this? i have tried putting her out before i go to bed, but she never wants to until i am attempting sleep. please help!!!!!
