Yes, it's perfectly OK! Don't feel so bad, often cats in shelters live in tiny 2x2 cages for months on end. She is much better off with you in a decent sized room than in a cage in a shelter! FIV is not very contagious, and doesn't live outside the cat's body, so, to answer the other poster's question, there is NO RISK of you transferring the virus to other cats on you or your clothes. Actually, the only way FIV is transmitted at all is by deep penetrating bite wounds, so it's actually safe to MIX a sweet, freindly FIV+ cat with non-positive cats, so long as they do not get into any serious fights. Most FIV+ cats show NO symptoms, and are carriers only, and live normal, healthy lifespans. There is no reason to feel bad for her, you are doing so much more for her than many other people would! There is a serious lack of education on the subject of FIV, and many shelters automatically euthanise these cats based on a test result. Even many vets are not aware of the studies done that prove how hard it is to transmit, or the treatment options available for symptomatic cats. There are LOTS of new studies available, and tons of info about FIV out there, if you just seek it out. I'll include a few sources below, please do take the time to check them out!
