Foods rich in lactoferrin are also beneficial for cats with hyperthyroidism.  Lactoferrin is a protein that can help inhibit thyroid-stimulating hormones.  This protein is found in some meat sources, but pumpkin seeds are especially rich in lactoferrin!

Lactoferrin supplements are also available if your cat does not like pumpkin seeds or is sure that she gets enough of this beneficial enzyme.  If she has liver disease or other health conditions, it is best to consult with your vet before giving her any supplements.

Do Hyperthyroid Cats Eat A Lot?

In many cases, a cat with hyperthyroidism may have a sudden loss of appetite.

This is because the disease causes their metabolism to speed up, and they burn through calories at a much faster rate than other cats without this condition.

If your cat does not take in enough calories, her body will begin to break down muscle tissue for energy.  This can trigger cat food allergies in addition to putting her at risk for other health conditions.

You should try to increase the number of calories in your kitty’s diet if she has already lost a lot of weight or is still having trouble eating.  There may be several reasons why your cat is not eating enough, even though it may be difficult for you to increase the number of calories she is taking in.

Some cats with hyperthyroidism tire easily and can become dehydrated if they do not drink enough water.  If your cat is lethargic or does not seem interested in her food, make sure she always has fresh water available!
