Sorry I can't help re: quarantine or vaccinations needed but can tell you that you cat will be fine here. Don’t worry about it being too hot, when have you ever know a cat to try to find the coldest spot to sleep or rest
They love the heat!
She may find it a big change if you are moving from a house with a garden to a flat and she has to spend all day inside but I am sure she will adapt. Our cat is fine in our 600 sq ft flat. She has never really lived anywhere else so does not know what she is missing but loves to spend the mornings in the sun on the balcony watching the birds.
Just make sure they have lots of toys to keep her amused
