Spayed cat can't walk, screams in pain, has lump. What should I do?

This is a serious emergency. She may have been hit by a car. You will need to take her to your vet right now, please. The vet will take xrays to find out whether her hip is intact, and her spinal cord. A hard stomach is a sign of severe pain either in the abdomen or spinal or hip area. Please take her now. She is likely in serious pain.

Poor Tiny! If you feel you can't wait until tomorrow for her to see a vet (and I agree it sounds like seeing a vet now is best for her as it sounds like she is in pain), I would get her into a vet right away. It could be she was injured when your nephew rolled on her. Please take her into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website. Best of luck, I hope this helps!

Poor Gracie! She could have fallen and broken her leg. She also could strained or torn a ligament. It's quite serious that she isn't walking on it and won't let you touch it. I would take her into a vet immediately for a lameness exam and x-rays. These tests will help diagnose what is causing this problem so she can be treated. In young kittens, it's important to get these problems checked out promptly to prevent any disruption to normal growth. This will also be very painful to her, and the vet can give her pain medications. Please do not give her any human pain medications, many are toxic to cats and are fatal if given. Only the vet can prescribe safe ones. Please take her into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.

If she is experiencing vaginal swelling i would suspect an ectopic ovarian cyst (this can happen regardless of the spay procedure. if this issue does not resolve after a while the solution is usually a surgery to look for the ovarian remenent cyst in the abdominal cavity.

Meow Meow sound very sick, and at this point in time, this is a medical emergency. You cannot treat this at home, there are no pain medications you can give her. Many human ones are toxic to cats, and are fatal if given. She has to see a vet now. Please take her into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.

That discharge is very abnormal. My guess is that she may have a pyometra (uterine infection). I suggest you get her to a vet as soon as you can. If you are not near an emergency vet she can likely wait until morning as long as she is eating and drinking OK. If she is acting sick then you need to find an emergency vet right now. This is not something you can treat at home. Best wishes.

If the lump is new then I would call the veterinarian and discuss it. It is very likely they would want her back in sooner if a swelling has started to appear in the last few days. It could be a simple hematoma which will resolve, but it better to be seen if possible. You can apply a cool compress to the area in the meantime. if she will tolerate it.
