Why aren't my kitties gaining love?

[Adana Ember]

I have four newly adult kitties... all 7 days old. One of them is 92% happy and has 9% love. I haven't done anything except provide milk and food. The other three are at about 75 to 80% happy and 0% love. They all have the same access to food and milk. Why would only one kitty be gaining love? They are all 'breed on' and partnered. Is there something I'm missing?



I got them over 90% happy, but still no love.
