The girlfriend left an ice cream pop stick around and I have just found it in Yuki chan house badly chewed on. 

They are used in Ice creams so I would assume they are safe for bunny to chew, anyone know anything on this matter?

A bit splintery but definitely not toxic. I have seen some cute bunny toys made from them. Just watch for any stasis incase she ingested any big bits but I would not be to concerned if she is eating and pooping normally.

The Japanese Pop sticks are really soft, there are no splinters in her house or any where else that I can see, You can bend the ones here, unlike the ones back home that would slap. I was just worried if they are bad for her. Today had a panic, she jumped on the printer table and took a bite out of a ink case, I tried to get her to spit out what she bit off but she swallowed it. I say it will no effect her as the size of the bit she swallowed would be less then 0.2mm, but now I have to change my living room again for the 4th time in two days.

You might want to invest in soe wooden chew toys for her. Check out the parrot section at your pet shop. Parrot toys are fine for bunnies and they are bright colours.Also some plastic stacking cups from the baby toy section of your variety store or super market. Just make sure all your electrical cables are protected if she bites into one of those she is a gonner.

The pop sticks are not harmful, though some can splinter so I think it's time for a wooden or willow chew toy. The ink cartridge may be a health risk. Try to feed her very wet greens and have her drink lots of water if possible, and eat a lot of hay. You're trying to make whatever she swallowed pass asap. Keep an eye on her and if she has any symptoms of pain (grinding teeth) or unusual lethargy, maybe get her checked by a vet. She should pass anything harmful within about 8-12 hours otherwise.

Yep. Bunny proofing is hard at first, but you get used to decorating Bunny Modern after a while.

She has a range of toys, but still is not happy, I have now removed anything that is plastic from the room to make sure she cannot get to it...
