You see a meticulously produced C shaped dent on the corner of ground beef you've left on the counter for defrosting, unprotected because you've forgotten you have a cat
When you are prepared to fight off competition to your snacks in a bag that sounds like a treat bag.
When you are on the cusp of sleep to have four paws pouncy upon you, causing you to scream and scare your husband.
You now have the habit of putting clothes away in a hamper in the closet because you have found more than one sock destroyed.
You get jump scared in the night by sharp curious paws tapping you leg trying to figure out what is under the blanket.
You have given up on deterring paw prints on the counter and shove dirty plates and such into the dishwasher after the "plates incident".
You have a blanket between your husband's pillow and yours for your furry companion to knead and suckle before running off... only to accidentally place your arm in a cold wet spot unsuspectingly.
