Bird vs Cat

Chloe was on an antibiotic for a while to help clear out some bad bacteria in her crop. She was acting fine and healthy before she got the medicine, but after the medicine she became a total clown! She would lie on her back and bat around an [empty] highlighter marker, swing from her cage and throw her toys at you while doing it, would hold entire conversations with herself, and at one point she hopped down and walked across the floor to the cats. She was there to boss them around, and the cats were a little freaked out!
