Hi and welcome to YT
!
I'm so very sorry about your loss, you must be just heartbroken. I hope you'll be able to find another furkid to love and fill your heart.
As for this breeder in NZ, I almost feel like your gut is telling you no...? It doesn't necessarily mean it's the wrong breeder, but maybe you're feeling too rushed or something..? I don't know. But I'd maybe wait a bit if it doesn't feel just right.
