There is no name change. Blue Diamond is Blue Diamond, and Platinum Diamond is Platinum Diamond. It used to be an agency cooperation relationship, but now they are doing their own things. I have bought and used the previous blue diamond Ever Clean, the current blue diamond, and the platinum diamond. Personally, I am still accustomed to using blue diamonds. The price of blue diamonds is slightly lower and the price-performance ratio is higher. Don’t question Blue Diamond just because it is a domestic brand. As for cat litter, as long as the raw materials are good, there will be no problem in using it.
