Yes I have heard about the cocoa shells being dangerous but I have never seen any.
JFYI. I did change out my mulch to “river washed rock” whatever the heck that means! Gradual improvement, mulch invites mold which invites fungus which invites parasites that love mold and fungus.
I have done every thing that I can think of to help my baby.
I only balk re: the raw food because we eat only organic and even the rice/burger treat for the runs is bad for her.
She loves deer poop and we are surrounded by white tails and wild turkeys, bunnies you name it!
Best wishes to all!
Good luck, this sucks.
