I'm a new player and want to get into ferus breeding. I lucked out by getting a felis cub from the giving tree and trading it for a female ferus cub at the TC. She's an adolescent now, and her heats are looming... As of now my goal is to get at least one ferus cub from her through her lifetime, but I'm not sure how I should go about this.

The way I see it, I should use her heats on ferus studs, which wouldn't even cost me more than 1000 sb in her lifetime (most likely, based on the prices I'm seeing now). OR I could do this while also providing the studs' owners with pennyroyals. This could drastically increase the amount I spend, which doesn't sound great as once again I'm very new and only have like a week's worth of sb stocked up, but it could definitely be worth it! Ultimately, I think if I spent 7 pennyroyal and received one ferus cub from the breedings, I would be satisfied. Then at least I could extend the lineage another generation and potentially make it my heir.

I am struggling to do a cost benefit analysis, however, because I have no idea if a pennyroyal provides a boost big enough to warrant this expenditure. My question is, based off your experiences using pennyroyal with 2 ferus parents, would 7 of these breedings yield a ferus cub?
