Giving your bunnies a mineral stone can cause bladderstones. I wouldn't advise it.

They really shouldn't get any commercially made treats. There is usually something wrong with all of them. They are gimmicks to sell to rabbit lovers. Other than hay, veggies, fruit and good pellets, a rabbit doesn't really need anything else, not even a salt spool. For chewing, an untreated piece of wood is just as affective and lots cheaper. If you want to make homemade treats, you could try this recipe but remember it's a treat and should be fed very sparingly. . 1 small carrot, pureed 1/2 banana, mashed until really creamy 1 tbsp honey 1/4 cup rabbit pellets, ground finely in a coffee grinder 1/4 cup ground oats, ground finely in a coffee grinder Mix pureed carrot, banana and honey in a medium bowl. Add pellet powder and ground oats. Mix until blended. Knead in your hands for 1-2 minutes. Roll out the "dough" in 1/8- to 1/4-inch thick layers between sheets of plastic wrap. Cut into small cookies (about 3/4 inch across). Place cut shapes onto a parchment paper covered cookie sheet. Bake at 325 degrees for about 30 minutes (check to make sure they are not browning too much). Turn off the heat and let the cookies sit in the warm oven for an hour or so. You can change the carrot to apple for something differnt.
