could you help me to convince the keepers in my country?

The only "Evidence" I could provide is pictures of our frogs.......they get rat/mouse as a treat ONLY and it happens every 3 months. Our frogs are chunky and "fat" but not obese. They are fed a staple of Nightcrawlers (earthworms) and do very well on this as a staple.

thx for your answer
