Unsuccessful update

[AlexandriteGem Resident]

My kitty cats are sick after the update. I clicked on the can, but it says no cats were updated and they are sick.

What can I do, please?

For sick cats they need food. 7 days with food. Or get a Get Well vitamin for each of them for instant healing goodness

The updater doesn't make cats sick, were they in inventory prior to updating? Cats get sick after 3 days with no food, current updater can is 1.56. Some much older versions won't update without help from KittyCats. If your cats were version 1.56 or 1.58 they won't update any further, 1.58 updates occur in the cattery not via a can.
Since you don't say what version you were updating from its hard to help more.
