my 1yr old female cat

Question
my female cat has been splayed and has lived around other cats since she was a kitten, I've had her for a year now and she's been fine around my other cat but she's suddenly turned really vicious towards the other cats and i don't know what's wrong with her

Answer
Hi
This is a common issue and can from nowhere sometimes. Because I am asked this quite often i thought it best to put a webpage together about the issue along with how to try and sort the situation out. Here is the page
