When I give my rats sunflower seeds, my rat Bonnie will take one by one from my hand and go put them in her bowl, while the rest of the rats are eating the ones she put in the bowl, she just keeps bringing them to the bowl, never stopping to eat one haha. Then when shes done, she goes to the bowl (i think to eat her "stash") only to find that there's none there, and then she begs me for more.
One of my boys, Max, loves to sleep on his back inside his bowl. Sometimes he looks dead because all of his fat body is inside the bowl and just his head and feet are hanging over the edge so I can't see his tummy moving from breathing, and it freaks me out every single time. haha.
