Big seeds with shells can choke Guinea Pigs, and seeds provide too much calcium for the piggies. Seeds are unhealthy for them. Once my cousin fed a sunflower seed to my piggie and she nearly choked. I was lucky I went in the room so I pulled the shell out.
Since the sun flower seed incident with my cousin, Ginny is starting to be scared of me :grumpy:! Thanks to my cousin... I think she's been secretly playing with Ginny and handling her roughly. Too bad Ginny's room doesn't have a lock!! :mad:
