1) In cats, constipation sometimes occurs if they have swallowed too much hair during their normal grooming. When hair gets into the digestive tract, it binds to the stool, making it harder and more difficult to pass. So, brushing him daily is a good way to help prevent this (not to mention it also helps with hairball issues).

2) A dirty litter box is not inviting to a cat and he may wait it out until fresh litter has been placed (or cleaned). In which case the stool will become harder as time passes and when he finally does decide to go it may be rather painful (hence the crying).

3)The intestines need large amounts of water to keep things moving smoothly. When water levels fall, stools get harder and drier and are more likely to stay in place. Is he drinking enough water?

3) Not getting enough exercise. His entire body, including the digestive tract, will slow down. And the longer they hold the stool in, the harder/firmer it gets (meaning more painful to pass his stool).

4)Finally, constipation may be a warning sign of other, more serious problems, such as kidney disease, infected anal sacs or even a hernia.
