In itself, this pet bed is very large (is used in my guinea pig and rabbit) The rabbit had it to gnaw joy green plastic insert, because I had to unfortunately take away because I was afraid he eats too much of the plastic. Especially since it is a pity about the product itself. My guinea pigs had at the beginning a little scared, because it's really big, but are now very much in it. Every now and then it must also be in the washing machine, as guinea pigs unfortunately are not quite as housebroken like rabbits. Otherwise, it's a very nice acquisition
