Longer Breeding Intervalls in the Cattery?

[Bea Shamrock]

I'm not very observant in that respect, but I keep checking on my online cattery kitties and sync each pair's sleep pattern as much as I can -could that be a factor Mal? It's easier to notice if they're asleep or awake inworld but in the cattery some seem to like to sleep more even after I've sync'd them (or so it seems to me)
