You're not alone. That is why we have a successful tortoise forum with tens of thousands of members. Everyone here knows why you are squealing!!! Its the same reason I take dozens of pictures of my tortoises eating. They do it every day, but it just makes me soooooo happy.This is how I feel every time my tortoise starts picking at his broadleaf weeds. I like squeal in excitement and no one in my house understands why it’s so exciting?
One thing I would suggest though, is to take lettuce out of the diet. If lettuce is in the food dish, he still will be slightly picky with certain foods and you can replace lettuce with much better options.
