I know it's perfectly normal for females to go off feeding for a while during breeding season, especially at ovulation. But do you also notice some of your males to stop eating during this time?
Yes, it's common. That's the reason to wait until males are a good size before breeding because they will stop eating frequently. They have other things on their minds.
Mine too! I like mine to be on the slimmer side and only feed them twice a week or so to keep them hungry but they are definitely pre-occupied with their lady friends around now and some refuse to eat. If they have extra weight on them then not eating is probably a lot more likely.
