Preventing Breeding Mode?

[Felidae]

I was just wondering if there is anything I can do to prevent my ball from going into breeding mode?

She's laid eggs before and weight wise never fully recovered from it. I don't think she could handle it again.

Is she living together with a male? If yes, you cannot prevent her. When she feels ready, she'll ovulate and will give eggs or slugs(the worst scenario the egg bounding due to her condition). But if you separated them before the last egg laying, you have really low chance that she have retained sperm.
