I don't think I spend enough time with Paco, even after 2 years, he still shakes when I get near him. He is 23 and I really don't know what to do. He had 2 previous owners that neglected him. I hand feed him his warm veggies twice a day, it the only way he eat them. I worry when I leave him alone, I finally found some pumpkin seeds and he adores them. I got home late last night and was eager to give them to him. I did our usual I have goodies, I have a treat for you, he took it out of my hand and threw it at me. I was like oh, so I gave him another one and he struck out fast as a snake and bit me, hard. I just felt so discourage, one, he hasn't bitten in a long time and two, I thought he would love the seeds. He is plucking more now, I have now changed jobs AGAIN, but its during the day so I am home more. I get so frustrated and welcome any suggestions.
