Our cat is quite thick due to illness and also not the youngest ... So I decided, a relief (against snorting climbing) and bed protection (we like to pull on the couch with the claw high) to get. The part was delivered quickly and the structure is simple. Quality is great and the staircase was used immediately enthusiastic. The cat has strapped it immediately, our cat but not :-) What isn? To scratch too low and too narrow to sit :-) So when it figured the cat, it is really great!
