Why is my spayed cat losing weight again after her medication?

It’s not normal for a pet to lose weight after being spayed. In fact most cats have a weight gaining problem after they get altered. I would recommend having her examined by your vet and also to have her stool checked for parasites. Most weight loss is due to an intestinal worm in pets this young. I hope everything works out well for your pet Savannah. Best wishes and take care.

If she eats very little but still gains a lot of weight it is not normal, she could be suffering from hypothyroidism which is an hormonal disease. you need to take her to the vet ASAP in order to have a blood test done first.

Cats can be prone to weight gain after being spayed due to the hormonal changes this causes. I would recommend switching her to a weight management food that is lower in calories than a regular adult diet. If you are able to, feeding her canned food only will also help, since canned food is less calorie dense due to its water content. If you want to leave some dry food out for her, consider feeding it from a puzzle toy like an Eggcersizer or Kibble Nibble - this way, she has to play with the toy to get the food out, which provides her with some additional exercise and also limits how much she can eat at a time.

She could have a different type of intestinal parasite that the particular dewormer you gave did not cover. If she is really active she could just be going through a little growth spurt and expending a lot of energy/calories. You could start offering her canned food twice a day as well as the dry food. Be sure she is still on a kitten food as it has more calories per serving. If she is still losing weight, I would have your vet take a look at her. Your vet will be able to do a fecal and even bloodwork to look for other causes of weight loss. I hope this helps!

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.

Overall being thin could be a result of an underlying metabolic, endocrine, or gastro-intestinal issue. (such as hyperthyroidism, diabetes,or inflammatory bowel disease) It would be best to have her evaluated by a veterinarian, and consider having blood work and urine tests run to see if there are any abnormalities. She is listed as unspayed--keep in mind that metabolism tends be slower once they are spayed. If everything on her lab work checks out to be normal, I would recommend you have her spayed for her overall health and for pet over-population concerns; another positive for her may be weight gain!

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Miss Piggy. I love her name! Very cute, Tony, and she is beautiful. I would speak to her vet about putting her on a weight loss cat food, and feeding her twice a day with measured amounts. That way, you can control what she is eating, and how much she is eating. You can also try to get her some exercise by playing with her. I hope this helps!
