I went through something like this with Sunny. Male cats have small urethras and they can get easily blocked. After a couple of expensive emergency visits (when we was doing the straining to go on things that were not his litter box) to catheterize him, the vet actually did exploratory surgery. Which was expensive, and she didn't find a blockage. But after cleaning him out, he never had a problem again. However we did put him on a prescription dry food - this stuff: http://www.entirelypets.com/felinecd2.html.
I used to buy it at the vet's - it's not horribly expensive, but it's meant for cats with this problem. Maybe the vet can tell you about it. It made a definite difference.
