Can my FeLV positive cat safely live with my vaccinated cats?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Female | spayed | 5 lbs

We took in a stray testing positive for feline aids & feline leukemia. We have 9 other cats, all previously vaccinated for feline leukemia, The stray has been quarantined in a 9' x 7' tent erected upstairs. Please advise whether the infected cat may safely mingle with the other cats. She doesnt bite, so Im not worried about her feline aids. Im hopeful she can mingle with the other cats because theyve all been vaccinated for leukemia, Thank you in advance for any advice on this subject.

It is obviously up to you about mixing the cats. I personally do not recommend mixing feline leukemia cats with negative cats. Even though they are vaccinated not all vaccines are 100%. The positive cat is still putting the negative cats at risk. They can spread leukemia by sharing water bowls, food bowls, litter boxes and standard grooming.
