My cats are 15 and both disabled and this works purfect for them. One can't jump because of an injured leg and the other one can't jump on the bed because she is blind so they use this as their stairs. It is easy to take apart and put back together and we recently sold our house and moved. We stayed several places in between and at each place I was able to put it back together for them to use and then take it apart again to move onto the next place. We didn't have much room in the car and it didn't take up much space so it was purfect.
