My Cats Eat Potato Peels. Is That Normal?

It sounds rare, but many pets display similar behaviour. This is due to many different reasons, one of them being the animals preference/ taste.

Don't despair - a few potato peels wont do much harm to the cats.

To answer your Question it is not normal for cats to eat potato peels.

It maybe a vitamin deficiency. What I did for my kitty's was just take a big (long not thick) sponge, put it on a plate of water then sprinkle bird seed on it. As soon as that bird seed grows, well I don't think it will- because my kitty ate it ALL before it even got 3 inches tall. Just keep it watered and in a spot that kitty can get it. It's also sold in some pet stores in a Lil kit, but my way is just as good and twice as cheap!!! Enjoy!
