An adopting a cat with a name question

[NinjaSmurf]

My cats Jack and Kali Ma both come to their names, as does my moms boyfriends cat, Jenny. None come on any other cats name, however they do come if they feel like they need loving (or a piece of whatever they think I have that's edible) too. Kali however does have a jealousy issue and while demand to be pet if she thinks she is being forgotten, even if it's because I'm feeding the fish lol. Poor thing doesn't do so well when I go away for too long...
