What a morning!

No idea how she done it but my kitten was in a cat fight and her tail was hanging off

Took her to the vets and he had to cut half of it
I what ti ask... will this effect her balance ?

Ah bless the poor little thing hope she feels better soon.

I'm not 100% certain on the balance thing but I have seen lots of cats with shorter tails happily wandering round so hopefully she will adapt.

Hugs to you both xx

Cats can live fine with shorter tails. I've had a cat whose tail was partially bitten off by its Mum as he was a runt.
