I Am Cait started off with over 2.7 million viewers, but has had a steep falloff to 800,000 viewers this season from those initial lofty first season numbers due to several factors.
There is a trans community backlash against it because of Jenner's constant missteps with our community that we finally got fed up with. Jenner's fab lifestyle doesn't match much of the way that trans folks do live their lives, and has angered others. Toss in her revelation that she is a Republican followed up by her laughable assertion that the GOP has been supportive of trans rights issues.

And it's not helping that you have the very popular Jazz Jennings with a reality show following her fascinating teen life on TLC.
So not surprised I Am Cait is now I Am Cancelled
