My girls didn't think twice about running up the ramp with the new cover. I was a bit concerned after four and a half years of running up a ramp that the cover might put them off but no - it was just fine except I did have to put some clips on the top because it slip right off the edge of the bottom. I wish I could add some pictures to show how I use it with my cat covers. I basically have skinny grids to extend the height of the cage by two grid squares and the area by the ramp has half domes to keep them from exiting the cage prior to the ramp installation so I just use the grid points that match up to the skinny grids. I like having my cage a little higher because I have seen bigger guinea pigs get out of a single grid high cage when they are terrified or tired of it. I haven't had that problem but the girls are loving their ramp cover so I had to make sure it would work.
