Hi. I'm a new member here and I would like to ask about my hamster. I have a pearl winter white hamster (2 months of age). And lately I've noticed that whenever I give her mixed foods, she always eats only the sunflower seeds. As I knew that it's not good for her health, I tried to train her by taking out all sunflower seeds and let her eat only what is left on the mix. I still give her sunflower seeds every 2-3 days for snacks.
But lately, I've realized that she has been really aggresive. She keeps on biting me, biting the cage (to the point it left marks on her face) and was a lil bit anxious running around. Usually she would just licks, sniffs and slaps my hand when I put it inside her cage, but now she always bites me! These days she has started to bury some seeds on her nest, but previously she doesn't put anything and I guess she's not eating much. Could it be that she was becoming aggresive because she's hungry?
