Is Royal Canin cat food "Urinary SO 33" the same as "Urinary SO"? I can't find any solid information on what the difference between them might be, or if it's just a re-branding. Urinary SO 33 is still for sale in some places (note name on the package in the picture).

I reached out to Royal Canin on Twitter. While this isn't a verified account, it is the account that Royal Canin lists on their webpage, so it should be trustworthy and written by someone from the company.

This is simply just a package change. You will only see it labeled as Urinary SO now.
