hi my cat is around 12, she has recently had a decreased appetite and appears to be losing weight. she has vomited undigested foodstuff in past. last night when i came home from work she didnt greet me as normal,, even when i went into room she didnt come to see me,she appears lethargic. she vomited what appeared to be a bile like substance. she appears to have not moved overnight and slept on the windowsill. She did not eat anything last night, however drank some water this morning. im not sure what she has eaten today as i am currently at work.
Hello, my name is***** and I have over 20 years of experience as a veterinarian. I'm sorry to hear that your girl Cheechy cat isn't feeling well with a loss of appetite, weight loss, vomiting and lethargy.
Vomiting and a loss of appetite can be related to eating something she should not have, too many treats or table food, eating foreign material (which could cause a full or partial gastrointestinal obstruction), chronic pancreatitis, esophageal reflux, a dietary allergy or sensitivity, toxin exposure, a viral or bacterial infection, inflammatory bowel disease, heartworm disease, hyperthyroidism (a tumor of the thyroid gland) internal organ failure, or even infiltrative cancers such as lymphoma.
Because she hasn't eaten normally in several days, is losing weight, and she is vomiting I am very concerned about her. If she isn't drinking enough to replace fluids lost with vomiting she will quickly become dehydrated and as her liver breaks down fats for energy to live she may develop a type of liver disease called hepatic lipidosis.
Ideally she would see a veterinarian. Simple stomach upset should pass within 24 to 48 hours. They could examine her, run blood tests and possibly check radiographs and/or an ultrasound to evaluate her and know best how to treat her.
In the meantime they can administer injectable anti-nausea drugs and fluids to rehydrate her.
There are some things you can try at home today if you cannot get her seen today.
At home to try and settle her stomach you can give either:
1) Pepcid ac (famotidine) at ¼ of a 10mg tablet per 5 to 10 pounds of body weight every 12 hours
2) Prilosec (omeprazole) at ¼ of a 10mg tablet per 5 to 10 pounds of body weight every 24 hours
These are acid reducers and may help her feel less nauseous so that she will eat and hopefully not vomit. They are quite safe and can be used long term if necessary.
You can use a medicine syringe to try and force water into her orally if she is refusing to drink.
Twelve hours after her last vomiting episode I recommend offering meat baby foods or a bland diet of 2/3 boiled minced white skinless chicken and 1/3 boiled white rice mixed with some low salt chicken broth to make it easy to lap up and swallow.
If she continues to not eat, or continues to vomit, especially if she has a fever or a tense, painful abdomen then she should see a veterinarian for an examination, diagnostics and intravenous fluids and supportive care.
Please let me know if you have any further questions.
