Love Levels Resetting?

[Reven Rosca]

I don't think this is a bug, but a feature.
I suppose you have a male and a female cat? In that case, they have had a kitten box somewhere within their range.

Kitties with breeding on will have kittens without being partnered as long as they belong to the same person and are in range of each other when the stats are right. That will make the love % drop to 0.

Love levels don't really mean anything other than that the kitties can have a box when they reach 100, and happines can be boosted with cuddles as well. This means that you can turn breeding ff and save 50% kibble if you don't want kittens.
