I just realized that the last 2 pictures of Belle is different. Her face marking looks much more darker than the older picture. In fact, I just noticed how 'black' Belle's face is now.
I suddenly recalled a certain something regarding how to maintain a Siamese's seal point (or marking or shade, whatever the term is). It's something like, if the temperature is too low, it darkens. Not really sure.
Also, I noticed that Elvee's fur is also darkening.
I'm sure it's nothing to be worried about but it seems kinda interesting to observe the changes throughout the old pictures to the recent ones.
Does this happen to your cat too when you keep them in air-conditioned rooms?
