They are fine for lay around pets but basically suck for breeding. I know many folks on here love lab blocks...typically mazuri and "higher end" sorts. Personally I feed dog and cat kibble. When I am feeding a bunch with tons of newborns I tend to toss in some higher % cat kibble. Sunflower seeds will add some fat...good for making milk.

But the stuff available in pet stores is great for pets. Not so good for feeding breeders. See if the store can or will order you some other stuff.
