It's good that you picked her on personality rather than colour.
After all, it's about interacting with your little beastie, isn't it. Even though cats would probably like you to gaze and admire them every waking hour.
I use PetPlan, but never had to make a claim Bit pricier, but they do have a good reputation.
Cat litter - Sainsbury's fine clumping litter or Worlds Best from Zooplus, bloody brilliant online shop for pet supplies.
I do put collars on my cats, but only the quick release ones. Only for the reason I put loc8tors on them. The elastic collars can maim and kill, so please don't use those.
To eat, mine get Applaws dry to free-feed on, and Animonda Carny or Cosma twice daily. Cosma is only a supplementary food, so make sure you have a good old read of the label when choosing a wet food. Butcher's Classic is well recommended on this board, not tried it myself though. I don't give my cats any foods containing cereals, because cats don't tolerate them well. (gives them the shits)
Regarding a scratching post, a good tall one, so she can have a good old stretch while stropping her nails.
And as Peas says, a Flying Frenzy. Get one of these for instant cat happiness. And don't forget the Dreamies.
