Mold anywhere is very bad for all animals, it can cause respiratory issues and grow bacteria. Since this is dried there is still the possibility your rabbit will eat it and that could kill your rabbit. If this is a show rabbit you ought to know how to care for it to keep it in the best possible condition. Even if its just a pet a clean cage is not optional. The fact you're asking here shows you're inexperienced, though common sense should have told you this isn't right. Don't write me off as a bleeding heart liberal. I'm president of my 4-H club and I've been around show rabbits, some close friends have breeding programs of several hundred rabbits. You need to take better care of your animal, even if its just a pet.

Brer Rabbit.
Rabbits who eat dry moldy feed at the very least will get diarrhea and a very bad tummy ache. Most likely it will kill them. If a rabbit is left to it's own devises in the wild they WILL NOT eat moldy feed. But if penned in a cage with moldy feed the rabbit is most likely to eat it out of boredom if nothing else.
The storybook rabbit who got stuck to the tar baby is Br'er Rabbit from the Uncle Remus stories, specifically the tale "Br'er Rabbit and the Tar-Baby" as written by Joel Chandler Harris.

No. They would get stuck in it unless it's dried up....but then again how could he eat it if it's dried up.
Blue periwinkles a stuck onto rocks by a string of dried mucas which acts like a glue.

It could mean that there is dried blood on it or maybe just a booger on it.
Touch it and see if it is still sticky or wet or see if the two items are stuck together.
