I have a very old (80-90 yr) CA desert tortoise and he has just woken up from hibernation this spring. He is eating well but seems to be having more difficulty than usual. He can eat grass fine but when it comes to his daily salad he has more trouble. We used to feed him in a pie-pan shaped dish that he would step on and then "flip" up to his face, but it looks like now the food just falls down where he can't reach and he can only eat the top half. I tried a sturdy plate and he just mushes it all over and bites at it without getting any. Any ideas? I thought about a feeding trough that is elevated so his horn doesn't get in the way. Any other ideas? [His entire enclosure is edible BTW with tortoise forage mixes and desert plants, but he doesn't seem to realize it because I think his previous home was just lawn and romaine lettuce]
