- FeLV infection is a common cause of reproductive failure in cats.
- Resorption of fetus usually occurs at 3-5 weeks into pregnancy, so pregnancy
- may have been confirmed by palpation of small fetal swellings.
- Resorption may be accompanied by a slight vulval discharge.
- Affected queens will often have had normal pregnancies previously.
- The mechanism of fetal death is not known, but may be due to placentitis or endometritis.
- If the fetuses survive to term, then the kittens will be persistently infected and are often sickly: FeLV is therefore a possible cause of fading kitten syndrome.
