While looking through my mealie cage, I found tons of those middle stage mealies. I took out a few and placed them in my uro's cage. He went over to them as fast as he could like he knew what they were. I fed him about 6 more. I plan on feeding them about once a month, for something different in his diet. He even isn't scared of me when I have them in my hand! He will walk right up to me and take it from my hand! It's pretty cool. I might be able to use these to tame my uro!
