Good point Heather!!!

Yes, maggots on an open wound or in soft poo on a bunny butt, will EAT into the skin and can kill a bunny in a couple of days!
That's why it is so important that you check you bunnies over, even if they are house buns, for open wounds and soft poo.
THEN the poo should be washed off and the area carefully checked, while any wound needs to be treated immediately and the bunny not allowed outside until the wound is healed.
