My cat is losing weight and hiding, but vet says she's fine. Why?

Updated on September 23rd, 2025

Pet's info: Cat | Domestic Mediumhair | Female | spayed | 8 years and 2 months old | 6.6 lbs

My cat, Annie, has lot 2 pounds since October of 2017. She has had a full blood panel and a body exam, all which my vet say are excellent. She eats in very little portions about 4 times a day. She will only lick wet food, so her usual diet is hard food with a little wet food here and there. She’s not as playful as she once was either. She spends about half her time under our bed. Any thoughts? We’re at a loss and currently waiting to see a new vet for a second opinion.

Poor Annie! I would make sure your vet has ruled out any type of intestinal parasites or bacterial infection including giardia and campylobacter. I would also talk to your vet about running an urinalysis and x-rays on her. The urinalysis will indicate any type of infection or crystals in the urine. On the x-rays, they will be able to look for any type of tumor in the abdomen or constipation/megacolon. Your vet can also send off a GI panel (cobalamin, folate, and pancreatic enzymes) to help rule out inflammatory bowel disease and GI cancer. Of course, you cannot completely rule out cancer with a normal abdominal x-ray and normal GI panel. I think the next step would be to do an abdominal ultrasound to look for any thickening of the intestines or enlarged lymph nodes. The most aggressive, yet most direct, diagnostic is an exploratory surgery with biopsies of the intestines. This is usually saved if all other tests are inconclusive. I hope this helps to direct you in a conversation with what may be the best option for Annie. I hope she starts to feel better really soon!

My picky cat is losing weight and has hairballs. Should I see a vet?

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!

My cat is losing weight, vomiting, and has blood in stool. Is she dying?

Poor Baby! It sounds like she has something more serious going on with her, and it could be that her anorexia, vomiting, and blood in the stool could be caused by GI tumors, GI polyps, irritable bowel disease, or a foreign body, among other causes. I would take her back into the vet for a physical exam, blood tests, a urinalysis, and possibly x-rays to diagnose what is causing her symptoms so treatment can be started. She may have something that's treatable, and her current symptoms do not necessarily mean she is dying. Have her seen by a vet in the morning.

My cat is very sick, not eating, skinny, and weak. When should I see a vet?

Annie needs to be examined by the veterinarian today. It sounds like she is very sick and there is nothing you can do for her at home at this point. Just like humans, pets can get sick for many many reasons. Some of these can be treated IF THEY ARE CAUGHT IN TIME. Other reasons will be fatal. Have her examined today to find out your options and so that Annie does not suffer if she is found to have something not treatable. Euthanasia is a hard decision but it relieves suffering. I hope this helps and best of luck.

Why is my senior cat losing weight and vomiting with normal bloodwork?

Poor Checker! This is a huge amount of weight to have lost in a year, so I would say that something is definitely wrong. In older cats with significant weight loss like this and normal blood work, the most common possible causes would be an intestinal absorption issue like inflammatory bowel disease (which can be present even if she is not having diarrhea), or some type of abdominal cancer. The next diagnostic steps would be abdominal x-rays and ultrasound, with exploratory surgery and intestinal biopsies if needed to get a definite diagnosis. If this isn't possible for financial reasons, a trial course of oral steroids and injectable vitamin B12 might be helpful - I would suggest discussing these options with your vet to see what he/she recommends.

Why is my cat weak, losing weight, and not eating after normal blood tests?

Poor Sachi! Significant weight loss and inappetence are certainly a major concern. I'm glad to hear that his blood work (I assume a CBC, chemistry and T4?) was unremarkable. However, foreign body intestinal obstruction/blockages, intestinal malabsorption issues that can cause inflammatory bowel disease (IBD) or exocrine pancreatic insufficiency (EPI), chronic pancreatitis, or cancerous processes, do not necessarily cause changes on screening blood tests. If Sachi has not yet had abdominal x-rays or an ultrasound, consider talking to your vet about these tests as his next diagnostic step. If he has a foreign body obstructing his intestines, this is a surgical emergency, and these tests would be helpful in obtaining a diagnosis. If pancreatitis, IBD or EPI are more highly suspected, consider talking to your vet about testing for vitamins B12 and folate, as well as TLI and fPLI. I hope this helps!

Why is my senior cat losing weight, always hungry, and has diarrhea?

These are indeed an unusual set of symptoms, thyroid disease and diabetes would be the first suspects for a cat with increasing appetite and weight loss. A specialist ultrasound scan of the abdomen may be worth while to investigate difficulties with food digestion and absorption or even tumours using up the calories

My cat is vomiting, losing weight, and has a huge appetite. Why?

Poor girl. It sounds like she's been to the vet and is hopefully under treatment. I can't tell from your question how long ago she had the reaction to the collar but get the impression it wasn't the last couple of days. I wouldn't expect on going issues if the collar was the only problem. If it's been more than a week or so, I would be suspicious that something else entirely is going on. Vomiting, diarrhea, and weight loss are the classic symptoms that cats get for nearly every disease, so it's hard to know what could be going on with her. If her blood work is normal, I would be concerned about something primarily with her gut such as Inflammatory Bowel Disease or Lymphoma. The next step is probably an abdominal ultrasound.
