You could try removing his food for a few hours to work up an appetite, then put in something he'd love like chickpeas and rice, piece of broccoli? A little chunk of cheese or maybe some egg. Zeelo (Madame LeFlocker) loves all these.
Zeelo thanks you for your kind words. She is cute and a royal PITA LOL! She dearly loves being out, eating tasty food and having fly bys. Going back into her cage is a bit of an insult to this little princess. You know you're well trained when after you fix her some breakfast, she gets a cup of tea.
She threatened to report me to the SPCA if I didn't.
