Anyone know why the canned version doesn't have DL-methionine? Its supposed to dissolve crystals but what is it in the canned formula? My vet only has canned til their order comes in. Debating getting RC or SD.

Hi. I have no idea why RC SO does not have DL-methionine in it. Might be a question to ask your vet, or even the company.
But, I do know that Hill's C/D does contain it.
Here are the actual ingredients in both:

Then that would certainly be worth asking RC about. Interesting...
Weird.... Their website lists it as an ingredient in the canned!

but did receive a reply I will post laterHow long has your cat been on SO for? If you want to switch I think Hills has C/D I'm not really sure it's much better though.
Another thing, is that my vet said that any wet food (if your cat is on that exclusively) works fine to prevent UOs and crystals. If your cats Uo wasnt to recent try talking to your vet about that as an option.

One of my cats is on Royal Canin SO. My vet claims it's the "best" one, and the rescue we got Austin from claims that this is the only one that cats eat consistently. I just checked the ingredients on the can, and I don't see dl methionine listed as one of the ingredients in the pate, but I do see it on the one with gravy (which I just give him as a treat now and then, he only eats the gravy).
