I want to go on a natural look in Arrow's cage since most of her toys are wooden. Are boiled rocks okay to put in the cage? If you made sure there are no sharp edges as well of course. I have a big stone that I brot home from Cyprus on my desk and Arrow loves sitting on it. I also have a few other white rocks from Crete, would they be okay if I boiled them?
Some german cages I've seen has had dirt in them (soil, earth, what you want to call it
) Has anyone on the forum tried this with their hams?
