I'm not really sure why but of our two cats I photograph Nelli a lot more. And she's not even that kind of a cat who would be pleased to pose. She might look at me straight in the eyes but when I quickly take my camera her head turns right away and she doesn't look back however much I call for her.
Tiitus is very confident and beautiful whereas Nelli is cute and afraid. Thus Nelli is easier to photograph outside as she keeps close to our house.
