Hi, I hope your bunny is OK,
a bunny not eating or not eating normally is something not to be taken lightly, My bun Coco likes to eat carpet sometimes I give her a papaya tablet occasionally ( papaya has an enzyme in it that breaks up carpet fibers and whatever else bunny might decide to munch on but she always eats her pellets and hay except when the weather is warm she mostly eats veggies and hay and eats little of her pellets. Hope this helps !!
