Wipe yourself & your cat's coat down with a Downy fabric softener sheet. My husband even walks around with a downy sheet tucked in his back pocket to repel mosquitoes. Try it, it does work here in Western North Carolina.
I live in Saskatchewan, where we have lots of mosquitoes, but I don't find that the cats are bothered by them. I think the mosquitoes are unable to bite through the fur. I suppose they could bite on their noses or ears, but I have never seen my cats bothered by them.
I would not use any repellent, as cats wash themselves, and I am sure it is not a good idea to ingest Deet (which is the only effective people repellent) or even any home remedy that people might suggest, like Listerine or Avon Skin-so-soft (which, by the way, do not work worth a darn).
