How To Tell If Kitten Has Feline Leukemia?

I have a kitten that is 13 weeks old. I got her from a family friend, she had been sick and they gave me my angel. She’s still very very young and has no idea what is going on around her at the moment. Is it possible for this type of cancer to be caught so early? Or is it just something you have to wait out? Should I be worried about anything else as well as this cat being ill? In general terms, how long do cats normally live with average conditions before becoming sick? What are some good ways for me to keep an eye on things with my new baby girl? Also, if there is any way you can tell by looking at kittens developmentally, does she seem normal overall or even the same as other kittens in general growth wise?”

Although feline leukemia virus (FeLV) can cause chronic infections in cats, most cats will never show outward signs of FeLV infection; however depending upon your particular situation these symptoms may include: weight loss due to poor oral health; unexplained gastrointestinal problems such as vomiting or diarrhea; inability to maintain body temperature (hypothermia); lethargy/depression; joint pain/limitation of movement; respiratory distress including coughing and sneezing; skin lesions such as ringworm and fungal infections. If your kitten shows any of these symptoms please contact your veterinarian immediately – he/she will make sure that all test results are reviewed and appropriate action taken. It would also be wise
