My cat gave birth almost 4 weeks ago and she has been fine since then. She has been nursing her 4 kittens and still being her healthy lively self. But I came home from work today to find her acting very strange. She's not moving, and breathing heavily. I picked her up and put her down in a different and she wouldn't move from there. I tried to give her a can of food(her favorite) and she wouldn't touch it. The kittens tried to nurse and she meowed in pain and rolled over. I put her on the couch with me and she hasn't moved since. Any idea what I can do? I am very worried

She may have an infection. Please contact your vet

3 strong possibilities all of witch I am sorry to report will require DR on the name tag.

Simply put foul or unhealthy girly parts, or Eclampsia. Kitten that missed the bus, and still inside mum.
