Thanks guys. Max and Speckles say MMMMEEEOOOOWWWW. I thought it was going to be C/D but the vet gave me a 4 lb bag of S/D and said he had to finish the whole bag up before going back to his regular diet. Apparently the S/D dissolves the crystals. In the meantime, he's been fine for the last couple of days; not straining and peeing OK, so I obviously caught it in time. The only other time he had crystals when right after I first brought him home 6 years ago, but I think that was because he was stressed and I tried all sorts of diets out on him. Back then, he did not take to the S/D at all and I had to crush it up and mix it in with wet in order to get him to eat it.

So tonight is his first helping. Wish me luck and thanks again for your well-wishes. I know this thread is not a serious one compared to what some of you have had to endure, but it's worrisome nonetheless.

Have given M & S headbumpies and scritches from all of you.
