Hi i have a ragdoll cat who i thought was pregnant,she was happy eating well and her normal silly self,her abdomen was large and i thought she was in labour,she was having contractions and eventually brown smelly fluid started coming out,having had kittens b4 i knew something was wrong,i took her straight to the vet where she was diagnosed with pyrometris.She had to have a emergency op,and has now fully recovered,thankfully but there was no indication that there was anything wrong!
