Thanks for your response.
however I fly over in August and the cat is following about a month after. The problem I have is that my mum and dad are elderly and their cats roam the streets and bring fleas in as soon as their rid of.
I will try my hardest to get rid of them and she is treated each month and has been since birth. She has never had them before but its since she has moved to my parents with the other cats, being outdoor cats and playing with all the cats in the neighbourhood it is impossible to keep them away from her.
If she was to still have fleas when her flight day came, would she still be able to fly ? or would she need to be 100% clear ? If it came to it and she couldn't fly, it would be difficult for me to arrange in Oz . If she will be unable to fly , I may need to arrange for her to stay in a flea free home for now with no other cats. that way I will be able to get rid of them now and there won't be a problem, but she is a very nervous cat and this will stress her out .
