My unspayed cat is losing weight. Could it be her heat cycles?

Updated On September 23rd, 2025

Pet's info: Cat | Persian | Female | unspayed | 2 years and 9 months old

I have noticed that my has lost some weight. I took her to the vet and after doing all her check up the vet said that she's completely fine. She eats perfectly fine and finishes her food much quickly. But i wanted to ask that since my cat isn't spayed and she comes to heat after every week so can it be the reason? Does a cat looses weight while she's on heat? I am thinking to get her spayed/neutered because what i think is that she looses her weight while she's on heat. Need an advice !!

Yes, indeed a cat that is not spayed and has to spend a lot of energy by going through heat will lose weight. If you do not intend to breed her, you should have her spayed, especially since cats will stay in heat until they get bred. She will be happier when she does not have to go through constant heat.
