I have found that after adding the fruits and veggies they don't eat as much of the rat diet. I believe they will eat whatever food they have until all their nutritional need are met, that may mean taking too much protein and just enough fat, but with the fresh veggies and suet, they can choose what they need and when. That gives them, expecially the grow-outs, vitamins, minerals, and protein for their meeting with the chamber of death, lol.

The suet cakes should probably be just thrown in the bin somewhere, I found that the lard gets on the hopper's wire cloth and attracts dust, not a good combo. They seem to like it, lasts them about a month for one block. If you lean it on the side of the bin, it keeps it from getting soiled.

The biggest reason I wanted to try the suet was I was feeding all my rats, including the breeders, Kent 23%. The mothers weren't getting enough fat in their diet and would eat some of the babies, bringing the batch count to 8 or so per litter. I tried the suet blocks and I haven't counted one missing pinky. Suet is cheaper than Mazuri and it is less wasted by the rats.
