Active cat not eating much & no poop. Is she constipated or sick?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Female | spayed | | 6.5 lbs

I've noticed that my cat hasn't been eating as much lately. For the past few days I've noticed less and less poop in her litter box and this morning there wasn't any at all. The cat is still active and acting just like herself. I don't know if she just doesn't like this food anymore or if she's constipated or if there's something more.

If she is not eating much than she won't be defecating much either. There are many reasons why a cat could have a decreased appetite including dental disease, infections, parasites, liver/kidney disease, gastrointestinal issue, constipation, palatability of the food, etc. You could try a different food and see if that helps. Otherwise, have your vet to an examination to help determine the cause and treat the problem. Your vet can do an oral examination to make sure she doesn't have dental disease causing pain and run lab-work and take an x-ray, if needed, to help diagnose.
