Birds nest in penstemon. What to do with it?

Out of the three types of penstemon I have tried to grow there is one that has taken very well to the garden here and I have over the last few years divided it to grow all over the place. The original plant has been cut down more severely this year than in previous years as it did not flower as well last year. I have also been gradually cutting down last years stems on some of the more recently planted offspring but found one today had a newly built birds nest in the middle of it. I remember now passing the spot when doing some weeding last week and a brown bird flew out from the area when I was close to it. There is nothing in the nest but it does look to be well made except maybe for the fact it is a bit too close to the ground considering the number of cats that visit the garden.
I think it might have been a thrush of some sort but I'm not sure has the nest been abandoned now that it has realised the area is not as free of traffic as it might have thought. The penstemon old growth looks a bit tatty but it would not ruin the garden to just let it be as there are plenty of other flowers and shrubs near it to hide it from view. Since the nest is empty should I just go ahead and cut the old stems down and allow the bird find another safer spot to try and make a new nest? I already found a baby thrush on the ground in another part of the garden a few weeks back and my priority really would be to try avoid the young getting eaten by the local cats which I regularly see hunting as they are farm cats that actually do catch some of their food. Any recommendations or advice appreciated.

Thanks for your advice. I had not planned on moving it with the intention that the bird might return to it but am worried that if I leave it where it is and the bird does lay eggs there that they will just become cat food. I have occasionally found wild bird eggs in pieces in the garden so I really think it is not the best place for a nest if the bird wants to continue to use it where it is. Actually thinking about it this nest may already have been raided as I saw a small broken egg about five metres from the nest last week. I know it sounds cruel to dispose of a well made nest but would it be better for the bird if it is forced to move to somewhere safer even if it means they need to start the nest building again?
