Our little green parrot person is like a shiny new leaf fluttering in the breeze as she hangs from the side of her cage and screams at everyone and thing in sight. After a couple of days of not eating, followed by me stuffing her with an entire refrigerator of sliced apple, pear and peach, Nikki is acting like nothing happened. Teasing the cats (calling Tut a "Rabbit!"). And daring anyone to stick their finger into her cage (ouch!).
Moral: Keep an eye out for any abnormal behavior from your pets. That’s "any" abnormal behavior. Being too quiet, hiding, not greeting you when you get home from work, etc. Even seemingly insignificant things. You can’t be too careful, and it may save their lives.
