Hiya please dont panic, we have bunnies here in the Sanctuary without any teeth.
What we do, is grate celery and carrot for veggies as these help keep the guts moving.
We cut up hay into chaff in a bowl and the bunnies eat that fine :wink:
We soak the dried food in warm water to make it soft (not runny) and the bunnies eat it quite happily.
You can feed a third of a jar of baby food once a day if the bunny cannot manage the grated food.
Bunnies manage fine without teeth, I know the thought of it is scary, but truly it is nothing to worry about, you just have to cut, mash and grate things up for him/her instead
hope this reassures you??
Good luck for the surgery tomorrow please let us know how your bunny gets on.
If you need any more help, you know where we are.
best wishes
