Yeah, as soon as we catch either of the cats dipping a paw in, it's time to pour that drink out, ha; our evil cat Kirara doesn't drink out of anyone's cup unless there's milk in it, which she is nuts for but I heard cow's milk isn't great for them really so she only gets a taste now and then, ha. But with all other drinks, she just prefers to knock your glass or mug over and watch with great satisfaction as it spills everywhere. She will purposely try her best to knock drinks over, she is one ornery critter. She figured out how to turn certain light switches off and on and if I won't get up and let her out of my room during the night, she will resort to hopping onto my dresser and reaching up to click on the overhead light switch cause she knows that always wakes me and I'll have to get up to turn it back off, since I can't stand to sleep with any lights on. But if I just leave the door open all night, my son's dog tries to come in and cuddle with me and Kirara hates him and has attacked him more than once when he's in my room. She sees it as HER territory; she leaves him alone for the most part in the rest of the house, but she's liable to leap on him and start shredding if he jumps on my bed. He is twice her size and scared to DEATH of her, ha.
