Query: Dangerous and disgusting, do not buy this for your pet

This product is dyed with some cheap chemical, in huge quantities. If you touch it, your hands will turn the color of the ball. If you touch it with a wet hand, you will be brightly dyed for 3 days. Luckily we realized this before our bunny poisoned himself. This is a disgusting and dangerous product that will hurt your pet. This amount of dye is obscene and unnecessary. Obviously unsafe.
