Siamese color fading

My seal point Siamese was a rescue 12 years ago. The last 2 years she's been taking medicine for hyperthyroidism. Could this have any thing to do with her fading, or is it just the heat? It is very hot where I live. She lives exclusively indoors, but my a/c doesn't work very well.

My seal point’s color faded with age

Color change in Siamese Cats

Thank you for your submission. From researching the side effects of hyperthyroidism medication in cats, there doesn't seem to be anything that should change their fur coloration. This is something that is temperature-sensitive, and the medication doesn't seem to affect body temperature, at least on a long term basis.

Though what is strange is that Siamese cats tend to get darker and darker with age. I had a Seal Point that turned almost all black, besides her underside by the time she was 10 years old. We lived in an area that typically had high temperatures, which was in Florida.

I would say that most likely the lighting in coloration will more likely have to do with it being very hot. But her fur should darken in the winter.

Thanks for bringing this up. I did not know very much about hyperthyroidism in cats.

And thanks for the sweet picture of your kitty,
