This Purina lawsuit is using the ingredient propylene glycol as the cause.
Interestingly a few years back they found propylene glycol to be harm full to cats. And they prohibited it's use but it is ok to leave it in dog food?
"It was known for some time that propylene glycol caused Heinz Body formation in the red blood cells of cats (small clumps of proteins seen in the cells when viewed under the microscope), but it could not be shown to cause overt anemia or other clinical effects. However, reports in the veterinary literature of scientifically sound studies have shown that propylene glycol reduces the red blood cell survival time, renders red blood cells more susceptible to oxidative damage, and has other adverse effects in cats consuming the substance at levels found in soft-moist food.
In light of these new data, CVM amended the regulations to expressly prohibit the use of propylene glycol in cat foods."

Question for our resident DVM Doug:
Is a cat's assimilation of propylene glycol that different than a dogs?
