Awwwwww but just like humans I'm afraid some cats are just moody pants.

My sisters cat is a prime example of this, she has a wonderful wonderful life with high quality food, all the rooms and love and attention a cat could want, occasional treats, a massive rural garden to roam, and even birds and mice if she takes the urge, but she still sits around throwing evils at everyone, and that's basically all she does!! Oh no sometimes she hisses too. Nothing will change this, my sister said she has been a bit moodier since the arrival of a little neglected 6 mnth old I gave her, but she'll eat with him now and nothing else, just sits under the furniture growling at him when he goes past, he is oblivious to her moods mind you, couldn't care less.

You cat is probably a Jeremy Clarkson of the cat world and you want a Felicity Kendall!
