Cat weight loss, vomiting...?

Question

My cat is an 11 year old female who has always been skinny. she usually weighs around 9 1/2 pounds, but during her yearly check up she weighed 8 and 1/2 pounds, and so we put her on a wieght gain diet (a whole can of fancy feast(small cans) instead of the one half she has gotten for the past 11 years) She has kibble whenever she wants it all day, plus gets scraps from the table.

Just yesterday, a bit less than a month after the start of her weight gain diet, she began to vomit clear, slightly yellow liquid (no food) there was no blood in it, and she has barfed at least 3 times over the last 12 hours. According to a family member's observations, she has been drinking a lot of water right before she throws up.

We are going to take her to the vet if this doesn't clear up in 24 hrs. we're keeping her inside (shes an indoor/outdoor cat) to monitor her food/water intake and such. Since the onset of her illness, she's been slightly lethargic and hasn't eaten much

Any ideas on what this could be? is it just a virus? she has had no history of this vomiting before.

Answer 1

there is a chance that it could be diabetes.  my cat is a diabetic and drinks A LOT of water and then from over drinking throws it all up.  definitely take her to the vet to find out if it is.  when animals have diabetes water goes through them fast.  so they keep drinking if you cat goes to the bathroom a lot then that is a great possibility.  good luck

Answer 2

Whenever my cats puke up that yellow clear bile stuff, it means they either swallowed something they shouldn't have or i fed them something greasey for that their belly's couldn't handle.  

Is it playing?

Answer 3

A 91/2 pound cat is not skinny so I am not sure what you mean by that statement, but the fact that your cat is vomiting, losing weight and is lethargic is concerning. I assume that your cat had some blood work the last time she was at the vet because one of the things that comes to mind is kidney disease, or long shot pancreatitis. I agree a trip to the vet is in order. Hoping it turns out to be something simple and treatable.

Answer 4

It's hard to say what's causing it. If she were mine I would withhold food for 12 hours and then retry. If she still vomits, definitely take her in.

I would also consider having her kidney values checked while you are in there. Excessive water drinking can be a sign of kidney problems.  

Answer 5

VOMITING - She may be ating too quickly, viruses, gut obstructions or fur balls.

If she is otherwise bright and alert, remove her food and water immediately.

Offer tiny sips of water after two hours.  Don't offer food for 12-24 hours.  If they eat or drink too early, they'll vomit again.

If she's quiet and listless, take her to the vet ASAP.
