What do you do if your cat has kittens and the placenta is stuck?

If your cat has kittens and the placenta is stuck, it's important to remain calm. Gently check if the mother is in distress; if she is straining or showing signs of pain, contact a veterinarian immediately. Do not attempt to pull the placenta out yourself, as this could cause injury to the cat. In the meantime, ensure she is comfortable and monitor her closely until help arrives.
