Thanks for that info. I will write it down just in case there is a next time. I took cantaloupe, blueberries, bananas, and Mazuri then cut up night crawlers and that what I was feeding him after I saw he was so thin. He was drinking tho. I did feel he was well hydrated, but I did feed a number of night crawlers and smaller slugs.Sorry for your lost Maggie. I've learned through the years that once a box turtle is very noticeably skinny that feeding heavy protein items like slugs/worms can actually make things worse. The mucus that those animals produce can dry up in the tortoises mouth and esophagus if the tortoise isn't responding to hydration. I try to stick to blackberries and the like for rehabilitating light box turtles.
Now if one is simply dealing with puffy eyes or ear abscesses then worms/slugs are usually just fine .
If you can get your boxies liking wheat bread ( mine love it) then if they get sick you can soak bread in a variety of beneficial liquids plus powder it with calcium and vitamins.
I'm rehabbing a rescued female who I was fortunate enough to get her eating bread and have had her bounce back nicely by both powder ring the moist bread and also squiring berry juices into the bread. As of last week she is heavy enough and strong enough to eat worms and heavier foods.
Just some advice in case another turtle catches whatever he was dealing with. Let's pray that doesn't happen
may I ask what the bubbles are in your soak picture? so sorry for your loss
