I love all 3 of my cats just as they are but if I could change something about them then:

Storm- I wish he wouldn't beg for food all the time and I also wish that he liked to be held and that he could become more of a lap cat.

Sunny- I wish that he wouldn't be so meowy in the mornings and late at night and that he'd cover up his poop all of the time.

Cirrus- I wish he'd let me pick him up and cuddle him and let me give him a belly rub and also become more trusting towards people.
