This is a nice product for the money.   Sturdy, easy to put together.   Lots of levels.   I have 3 cats, One (the youngest) started using it right away up on the 3rd level.   The other 2 ignored it.   After a couple of days the 1st cat stopped getting on it.   One of the other cats went into the box to nap one time, but after that the cats haven't gone near it.   I am not sure why, maybe they are too old.  They are 5, 10, & 12 yrs old.   I do have a friend who does Siamese cat rescue, so if my cats continue to avoid it, I will probably give it to her.  I would have given it a 5, except that the cats won't use it.
