Will you kick me when this stuff comes up? I can't keep up with the dang notifications I get, between venganza and fecesbook, and work, and fambly and all... I just had to go through 260-odd emails this morning, and there'll be another 200 by tomorrow. stupid bloody world full of people...argh.
Anyway, it''s not odd for a cat to develop something later rather than sooner - Squeekie and Elvis didn't get their digestive problems until they were 8 or so years old, and I think all the ones that have had urinary problems over the years developed them later in life. You just have to be more stubborn than Max, Twisty. We've occasionally had to syringe-feed some kinda vet-food to one or another of the cats for a while to sort of jump-start them to eating it. Sometimes a flavor enhancer will work, putting some kind of groovy gravy on top of or mixed in with the recommended chow can get them eating it, but not always.

Little bitty spots can mean he's trying to pee more than he actually needs to. We use micropeeing as an indicator of urinary track infections (the cat feels like s/he has to pee when s/he really doesn't) but it can also indicate partial blockage (need to pee a lot but can only get a little out) like that caused by crystals. We also had a circumstance where Harry had a tumor growing in his bladder that took up a lot of the space and made him pee a lot of little pees.
I assume you have several bowls of water out for them that you change at least once or twice daily - have you thought about getting them a fountain? We have two of these:

They seem to get a lot more action than the other dozen bowls we have for them. Sometimes splishy water will encourage a cat to drink more than s/he might otherwise. Peete will come to drink out of the faucet every time we turn it on, and Dood sticks her head under the flow from the fountain, but that might just be because she's old and senile. They also like to drink out of places that they shouldn't, like pans on the stove or glasses in the sink. You might try leaving some surprise water around for Max to discover.
