Monster will normally sleep thru most things. but when he hears dry food being poured into his bowl, he will be awake and in the kitchen. also the treats being shaken. & when its time for wet food & i call out,"babies, time to eat!" he will be right there.
Mittens is a really light sleeper, so just about anything will wake her. if shes in another room sleeping on the bed & i walk in the room, she hears it no matter how quiet i am. just the other day, i went in the room & she was sleepin so heavily for once, she didnt move. her face was literally IN the blanket, & i was afraid she couldnt breathe. i pet her, she didnt move again, which suprised me, so i checked to see if she was breathing, since her sleeping so heavily is unusual. i moved her head so she could breathe better, & yet again she didnt wake up. a while later, i put dry food in both of their bowls, & that sure did wake her up, from the other end of the house.
