Hi, Could anyone tell me if a cat gets much larger after 7 weeks of pregnancy? Bluebell seems very large and the kitten shapes seem big, i'm afraid that she will have a lot of trouble giving birth if she gets much bigger. She is approx 7 weeks 4 days, although the vet said she may be a week further on. She was seen with a boy and the date would equate to her being 7 weeks 4 days. Oh i'm so confused!!!! She is a british short hair but the father ( i think ) is the local Mr Tom from up the road!!!!
