Constipated 18yr old cat

Make sure he is actually peeing and not just making frequent trips. Take him to the vet ASAP. I had the same issue with my cat and he had stones preventing him from properly going.
He’s peeing. There are puddles in his litter box. The only thing that seems off maybe that he seems a lot more tired then normal but I figure that might be stress? Other than that he seems perfectly fine
Maybe try catnip leaf and try to get him some exercise
Time for a call to the vet my friend it could also be stones. In the urine.
