I was at the petship in SM Cebu today and found this for sale, its like dog food but for reptiles. They also even have a special one for lizard and turtles as well.
Then I looked at the container and I found that they have a website: http://www.sera.de
You can click the american flag at the side to get the english version:
Herbal food for tortoises and herbivorous reptiles. sera raffy Vital is a blend of herb and food pellets that is readily accepted by all herbivorous reptiles.
I don't know. I have something similar that's formulated just for dragons. Gibby doesn't like it. Since it's just for herbivores, you'd still have to buy live feeders, and for me, anyhow, that's the expensive part. I'd rather buy fresh veggies I know are good for them than something that might not be.
