as her mum is most likely being spayed this summer so I can never have another kitten from this combination.
But Boopys doesnt really care about that does she ?
It probably wouldnt seem so bad if she had normal type seasons but since she started so young and then was only by what you have said yourself getting 2 or 3 days off inbetween her seasons it sort of makes it all the worse and more critical she doesnt go on for too long, I thought most breeders didnt like their maiden cats to have more than 4-6 calls before mating and pregnancy.
What were your plans if she gets pregnant in sept & successfully has the kittens, are you going to leave her entire to keep having so many seasons until she's given you what you want & the exact type you have in mind ?
You love your cats i know that but looks like your storing up a heap of trouble for the future, Bilbo still has that testicle in his scrotum left aswell doesnt he & you dont need him for mating ?
