My cat is losing weight. Is her current food causing the problem?

I would recommend having some blood work performed on your cat. Hyperthyroidism is a common disease in middle aged to older cats that causes an increase metabolism so cats are often very hungry but unable to gain weight. I would also recommend having your vet check a fecal sample to ensure that Koda does not have any intestinal parasites as this can cause weight loss as well. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

Hi! It does concern me that Myla has lost a noticeable amount of weight over the past few months. It's certainly possible that this could be due to her picky eating habits, but I wouldn't necessarily expect her to lose a considerable amount of weight from that alone since I'm assuming that she's always been a bit picky. Other causes of weight loss can include inflammatory bowel disease, a heavy burden of parasites, cancer, kidney disease, or diabetes, although we often see other changes associated with many of these conditions. I do think it would be best to take Myla to her vet for an exam and some diagnostic testing (blood work and/or imaging - x-rays or ultrasound) to try to get to the bottom of this situation. Until her appointment, try feeding her wet food in a room away from your other two cats so that you can more accurately see exactly how much she's eating. I hope that everything goes well!

A 3 pound weight loss is indeed significant and not normal. There could be many reasons for this, and there is just no way to pinpoint the cause without a hands-on exam and possibly blood work. I suggest you take your kitty to a veterinarian for a wellness exam.

If he's on a weight loss diet prescribed by your vet, then it may be that he just isn't used to getting "less" food. Feeding a higher fiber diet (most weight-loss diets add fiber) can help him feel fuller on less food, which can help with his being hungry on fewer calories. If the problem continues, ruling out any issues such as metabolic problems is also a good idea to make sure there isn't an underlying cause with it. You may also want to spread out his meals to several more throughout the day, instead of just 1-2 large meals, so that he feels like he is getting "more" over a longer period of time.

When an senior cat is eating more frequently yet losing weight, this can be a sign of hyperthyroidism. With hyperthyroidism, the thyroid gland is secreting too much hormone which causes an increase in the pets metabolism and subsequent weight loss. Have your vet check Hopes T4 levels to see if she is hyperthyroid and in need of medication to help stabilize her hormones so that she doesn't continue to waste away. This is easily diagnosed and treated with medication (i.e. Methimazole). Your vet will also want to run baseline bloodwork on your pet to make sure no other disease processes are there.

Hello, and thank you for your question. Disinterest in food and weight loss are red flags, and I would be concerned with a medical issue causing these symptoms. I would recommend a visit with your veterinarian in the next 24 hours. They can perform a head to toe examination, assess for pain or discomfort, dehydration, or fever. Possible causes include infection, pancreatitis, gastric foreign body, or inflammatory bowel disease. Your vet may recommend blood work or ultrasound to help reach a diagnosis. In the meantime, continue to offer different types of food and free access to fresh water. Monitor for any vomiting or loose stools. I hope this helps, and that Kika feels better soon.

I definitely think you should have Dahlia examined by your veterinarian. A few diseases that could cause an increased appetite with weight loss include intestinal parasites, diabetes, and hyperthyroidism. Your vet can examine Dahlia and her stool, and may recommend checking lab work if parasites seem unlikely. All of these diseases are very treatable, but it's important to get a diagnosis quickly.
