I think her personality tends to show through in her photos, both normal and IR. She has this very sad look all the time and is a loner as she does not get on well with all the other cats.
But 'IR-photographically' speaking, IR pics of cats are kind of interesting too. They still look somewhat normal to a viewer, especially one who has not seen what the cats actually looked like in visible light, maybe a bit like sepia-toned, unlike trees where the leaves looked white in IR.
The one thing that do look strange in IR photos of cats is the colour of their noses. Reddish or pinkish noses tend to show up as white or whitish like in the last 2 shots and that don't exist in real life. That could come across as 'interesting' in a hard-to-pinpoint way.
