Absolutely! Again, I'm not sure that these differences are the reason for some cats' current symptoms. The changes are very minor- sorry if I made it sound like the ingredients had changed- it's primarily the order of ingredients that has changed, which could mean that the ratio/amounts of these ingredients is different in the new cans. Here goes:
OLDER CAN (note that I already recycled older cans with an expiration of March 2018 - # unknown, but this last can dated June 2018 has the same ingredients as the March 2018 cans and I haven't had any issues):

Ingredients: (blue font = different order of ingredients than above; red font = different than above)

If anyone has even older or newer lots, I would be interested in seeing if there are more significant changes.
