My cat is 8-9 years old and has had 3 litters of kittens healthly, she became pregnant with the fourth but they had to be removed as the pregnancy could cause her,the kittens to die;i didn't want to risk either so she had an operation. Its been around 5 or 6 years now and over the last few weeks her stomach has became bigger by the week is it possible that she could be pregnant? When she had the operation I'm not sure weather she was neutered or not and would like to make preparations if kittens are on the way
