What about the seed sticks you get in shops, what are those bound with?
Honey and sugar! Hate to point out but just because they are in the shops doesn't mean they are good for your pets lol :lol:
I had an idea for christmas pet treats not sure if it's any good though...
You can buy baked apple slices and vegetable crisps, but most have oil and salt (or sugar) added.
I don't see why you couldn't make your own and carefully bake them in the oven on a non stick surface so you don't need to add oil. If you want really thin crisps use a vegatable peeler.
You can use carrot, apple, beetroot, squash, parsnip etc and you could even use cookie cutters on the larger veg to make nice shapes to hang up like edible bunny's Christmas decorations!
I know you can thread popcorn to make garlands, but as far as I know that's not a good bunny food, but I don't see why you couldn't thread bunny friendly foods/treats!
I wonder if anyone could make stars out of a mix of straw (for stiffness) and hay to make bunny safe/edible decorations too!
