Ya know. Cuttle bone that you give to birds for calcium? Well, I grind it up and give it to my geckos for their calcium. They do outstanding on it and talk about how much cheaper it is. So! I gave it to my mice and they chewed it up in a day. So I'm wondering if its a good calcium supply for them as well, plus I'm sure its good for their teeth. Anyone?
My mice like the mineral stones (not grit stones) I get for my pigeons (same composition as the rodent stones, but bigger and cheaper). Although some will chew up the entire stone into little bits for fun and destroying it in the process.
I have to buy cuttlefish bone for my finches. Sometimes I will throw a chunk in with the meece but they don't seem to touch it. I give nursing and pregnant does scrambled eggs, however, and I have been known to put ground cuttlefish bone in there.
Yeah, mine only get it when they're busy making nutrients for their babies (males never or almost never get it). I've also mixed millet in with the eggs. You can use your imagination, really. The mice don't care if it doesn't look the prettiest.
If you think the budgie seed is like popcorn, give them some of the millet still on the spray (sold for birds)! Mine devour it as though there's no tomorrow!
Willow, if you wanted to add mealworms to scrambled eggs, I don't see why you couldn't!
One other thing: when I make scrambled eggs for my mommas, I prepare it with human infant formula, not regular milk. I do this to make sure it's as chock full of protein, fat, and nutrients as possible so the growing babies get good nutrition.
