animals are creeping me out....

i swear it's like they don't want me to sleep ever again. the puppy has been demanding to go outside at odd hours. mainly to check behind the cabinet/ little shed on the porch. sometimes she barks and growls at it. then carlos likes to stare intently out the window into the dark. i keep telling myself it's probably neighborhood kitties, or possums. last night roxie kept pacing around, grumbling, i finally gave up trying to go back to sleep about five thirty and let her outside. why don't they listen to me when i tell them to chill?
