If so there is a lot of debate on how soon one should wait before bringing in a new cat (esp kitten) I'd recommend it's vaccinated either way. While rare, a cat even on an enclosed patio can be exposed.
Feline leukemia virus will not survive outside the cat for more than a few hours in most environments. However, FeLV-infected cats are frequently infected with other hardier infectious agents, and these may pose some threat to a newcomer. Thoroughly clean and disinfect or replace food and water dishes, bedding, litter pans and toys. A dilute solution of household bleach (4 ounces of bleach in a gallon of water) makes an excellent disinfectant. Vacuum carpets and mop floors. Any new cats or kittens should be properly vaccinated before entering the household.
quick google for a recommended cleansing for an area where a FeLV cat may have existed.
Good luck and get the cat it's shots. To many people ignore taking their cats to the vet although they take their dogs.
