I'd suggest against spaying
If you love her but don't want to breed her, just keep her around for a bit and see how it goes
You don't have to accept the new Doe if you don't want to
I never said you couldn't, those people are most likely those "pet rabbits people" who barely do their research and probably treat them like a cat or dog
Go for it if you want to ig, but I'd advise against it
I don't take mine to places like public parks for many reasons, but I have a few harnesses that are just fine to use out in the yard
A few of mine are trusted outside without one but I don't recommend it unless you know for sure they won't run away or hide somewhere
Pretty sure they meant the Kits have been in there for too long to be normally formed
Anyway, it's not unusual for Does to have Kits later than 31 days and I've had a Doe have one around 3-4 days late and he was born with fur already
