She's been in blue for 2-3 days, so it shouldn't be too long now! The image is from her day 1 of being in blue, she was cruising around like crazy to scout out a cozy spot. She's settled (and immediately pooped) in her warm hide, and stayed in there since.
I was actually a bit worried about an RI before the blue, because she started whistling!! But apparently that's more or less normal for Black Pastels because their noses are weird :')
I also guessed it was AI-generated, did not realize how inaccurate it was. Thank you for all the corrections, it's super informative!
