My two cats (4 and 5 months old) love this Rustle. He is colorful, stable and non-irritating crackling. It is very good that it does not coincide or will collapse at some points in itself. For brevity, it is optimal to traverse. But as a place to sleep it is like liked. The hole in the center and the attached ball at one end are a well thought-Plus. Generally, a great price - performance ratio!
