What is Anorexia?
Anorexia can be categorized into two types: true anorexia and pseudo-anorexia. True anorexia describes a cat that does not want to eat and won’t, whereas pseudo-anorexia describes a cat that wants to eat but cannot due to complications. Disease, tumors, inflammation, and pain are common causes of anorexia in cats. A cat that has stopped eating for any reason is considered to be in an emergency situation, as starvation quickly causes life-threatening hepatic lipidosis in felines.
Anorexia in cats is the term used to describe a sustained partial or complete loss of appetite. Your feline may appear uninterested in her food or she could try to eat, but leaves the food bowl soon after. Anorexia is not a disease in itself, but rather a clinical sign of an underlying disease or health complication. Anorexia can be the result of pain, cancer, systemic disease, and abnormalities with the structures that occupy the mouth. Detection of anorexia at home might include the unwillingness to eat, dramatic weight loss and hiding around the home.

  • Gastrointestinal blockage
  • Cancer
  • Pain
  • Loss of the ability to smell

Diagnosis of Anorexia in Cats
The diagnosis of anorexia in cats will begin with a differential diagnosis between true and pseudo-anorexia. It is at this time the veterinarian will ask you about your feline behavior, focusing on her interest in food. The doctor will then review the cat’s medical history and conduct a thorough physical exam to reveal the presence of any irregularities that would prevent the cat from eating as usual. If the presence of an abnormality is unavailable, the veterinarian will choose to perform a variety of diagnostic tests including: 
  • Blood work, including a complete blood count, coagulation profile, and serum chemistry profile
  • Blood pressure analysis 
  • Thyroid testing  
  • Urinalysis, focusing on evaluating the kidneys through the evidence of increased bilirubin
  • Abdomen and chest ultrasound
  • X-rays 
  • An endoscopy 
  • FeLV testing 
  • FIV testing 
Treatment of Anorexia in Cats
Treatment of anorexia in cats focuses on treating the underlying condition that was found during diagnostic procedures. However, the veterinarian may provide supportive therapy to the feline to reverse dehydration, decrease nausea, and provide nutrition. Initial therapy is usually completed intravenously, but if the feline has not received adequate nutrition for greater than three days’ time, a feeding tube may be placed. The treatment plan your veterinarian chooses to address feline anorexia greatly depends on the underlying cause and how your feline reacts. Some cats’ underlying disease prevents them from tolerating food in the stomach, therefore an IV line may need to be placed to provide adequate nutrition. Nutritional therapy treatment requires hospitalization of the feline, as this therapy cannot be given at home and poses a risk for infection. The veterinarian may also choose to prescribe medications during the treatment period which could include: 
  • Steroids (inflammation reducers) 
  • IV fluids
  • Antacids 
  • Pain medications 
  • Appetite stimulants 
  • Anti-nausea medications

Recovery of Anorexia in Cats
The prognosis for anorexia in cats depends on the underlying cause, the severity of the feline’s condition, and what the veterinarian has found present in the cat’s blood work. In general, a feline that refuses to eat has an overall poor prognosis. Your veterinarian will ask to reevaluate your feline periodically after the cat has been released home.

Thank you for your question. I'm a little confused by your question, in the symptoms you say he is vomiting and having diarrhea, but I'm not sure that you mention that in your actual question? If he is vomiting and having diarrhea, and has lost appetite, then it would be best to have him seen by your veterinarian, as kittens can be affected by parasites and infectious diseases, and he may need treatment. If he is bright and happy, and not having any diarrhea or vomiting and seems to be hungry, you may just need to try a different food for him until you find one that he likes. Kittens don't tend to be as picky as older cats, but there may be something that he likes better. I hope that all goes well for him.

My pet has the following symptoms:
Anerexia
Hi, my 13 year old cat has had a relapse of cancer. We know it's terminal, it has spread through the chest. At this point we are doing palliative care to keep her content. She currently is getting SQ fluids every other day and a daily does of an NSAID pain. I believe it's pirexicam or something like that. Two weeks ago she was less interested in her set food/would eat only some of it, but being a picky eater it wasn't completely unlike her. A week ago she came, sniffed, and walked already. Weird. The next day she refused to even come inspect the way food and we noticed she wasn't eating at all (they are free feed kibble) She still drinks but doesn't eat. She still drinks frequently but has lost a lot of weight and only moves to find a new place or grab a drink. We understand she's in the end stages of her disease but sometimes she looks like she wants to try to eat. She will eat the odd treat but stops after one or two. We've tried baby food, kitten food, wet food, ppl food that she normally begs for. She was given an appetite stimulant and she did eat a little after that but it was short lived. We currently syringe feed her at night to give her her pain meds. We are at a loss as to how to encourage her to eat a bit more

If TJ doesn't feel well enough to eat despite all of the things that you have tried to coax her to eat, that may be a sign that her life is not of great quality, as hard as that is to accept, and as sad as that is. All you can do at this point is offer her anything that you think she might like.

My pet has the following symptoms:
Appetite
My cat has hypothyroidism and has started taking felimazole for it but it has made her loose her appetite completely. I have given her the most tiniest bit of mirtazapine and she started eating. But effects only lasted a day. I decided to halve her dose of felimazole to just 2.5mg a day to help her eat. Can i give her both these medications together? She's too thin and weak. She needs weight on her now.

You can give those two medications together, but it is concerning that the Felimazole has caused a decrease in appetite. It is important to monitor blood levels of thyroid hormone while figuring out the right dosage for Jenny to be taking.

My pet has the following symptoms:
No Meow, Wont Eat Or Drink Or Come
My cat stopped eating and drinking 2 weeks ago. I took him to the vet who gave him pills for appetite and stomach discomfort. He appeared better and began to eat and drink. Now all of a sudden he's back where he started

There are many different causes for the loss of appetite and it is important to determine the underlying cause, without examining Tiger I can only recommend basic supportive and symptomatic treatment which isn’t going to resolve the underlying issue; you should return to your Veterinarian for a thorough examination to see what the underlying cause is.

My pet has the following symptoms:
Lethargy, Anorexia, Weight Loss
My kitten is not eating. She is less active, sleeps more, but is playful when awake. My vet did give her SQ fluids and said she is just taking longer to recover from a distemper vaccine she just had. She ate a little A/D but is now not eating again. She has lost almost a pound. I am very concerned about this.

A lack of appetite and a loss of weight by be due to various different conditions including side effects of some vaccinations, it is important to ensure that Bella is hydrated (fluids are great) and try to encourage eating by hand feeding her or mixing a little smooth wet food with water and syringing it slowly into the mouth drop by drop. Keep monitoring her and return to your Veterinarian if there is no improvement. Regards Dr Callum Turner DVM

My pet has the following symptoms:
Loss Of Appetite
Loss Of Appetite, Throwing Up
My cat is around 2 years old. He is playful and a great loving boy. In October he started to throw up blood. He was treated for an ulcer. About a month later he stopped eating and drinking for 3 days. The vet did blood work and it was clear. This eating on and off went on for 2 months. I treated him with an appetite stimulater and nausea meds on and off. He pukes during this time usually. I have tried so many foods. Along with a GI food he has been consistently on. He stops eating but seems hungry and wants to eat but will not. This will not stop. Vets thought he has a blockage and operated. They found nothing, we are waiting on biopsy reports. He has stopped eating again 6 days post op. I am completely frustrated and about to give up. What is wrong with my cat?
