Physiological birth in domestic cats encompasses the period during which  foetuses  are  expelled  from  the  birth  canal  through  uterine  contractions,  cervical  dilatation,  and  abdominal  contractions.  This  process varies    in  cats   but   generally takes    about    8 h.   The   term    “inter-rupted  labor”  refers  to  cases  where  the  physiological  birthing  pro-cess it is not entirely completed, despite an apparent completition of parturition. In cats, birth typically terminates within a few hours (ap-proximately 90%) during the second stage of labor. Labor has rarely been    recorded to  be  completed within    24–48 h (around 0.3%).    In  our clinic,    a  Van   cat   was   presented with    incomplete labor    54 h   after    the first delivered kittens. To the best of our knowledge, such a case has not  been  previously  documented.  The  2-year-old  Van  cat  was  pre-sented with complaints of difficult labor. In this cat, two live foetuses were  born  normally  at  45-min  intervals,  but  labor  ceased  after  the  second  kitten,  as  identified  by  the  cat  owner.  After  a  lengthy  wait,  the cat was admitted to our clinic as an emergency at the 54th hour. The  cat's  full  medical  examination  revealed  that  all  health  param-eters   were   normal. Ultrasonographic and  radiological examinationsidentified numerous live foetuses (200/min heart rate) in the uterus. Consequently,  an  emergency  caesarean  section  was  performed  in  consideration of the elapsed time, leading to the successful delivery of six healthy kittens. In conclusion, this case demonstrates that Van cats  may  experience  interrupted  labor  because  of  hyperfetosis  (8  foetuses) and subsequent uterine inertia. More research is required to confirm this hypothesis.
