After much online research, I went with the HPW. He loves it and cleans his bowl every night. He gets:
* 1.5 tsp HPW mixture
* small bowl fruits and veggies (I'm working on finding stuff he likes with a
good calcium/phosphorus ratio, but I'll be talking to my vet about that
soon)
* small bowl pellets
The pellets get left in the cage during the day for snacks.
I've tried giving him meal worms for treats, but he tends to take them from my hand, drop them, and then go on doing whatever he was doing. He likes apple sauce much better (the natural stuff, that only has apples and water in it). I've given him a dab of yogurt for protein, but I think I might try crickets to see if he likes those better.
As I've said, I'll be talking to my vet about it soon, but any comments are suggestions are welcome. I want a happy, healthy little boy!
