Cabbage, I tried hanging it up and it was hanging for three days. I took it down and rolled it across the run for them and they pounced on it.
Carrots, either grated or boiled whole.
Melon, and melon seeds.
Zucchini, home grown until it's HUGE with massive seeds inside. I cut them in half length ways.
Pasta, although it's not the best treat for them.
And of course meal worms and crickets. I get them from the local pet shop. I don't feed insects in the warmer months. They can catch their own.
