Older cat with vomiting and white nose.

Dr. Marie replied:

Thanks for your question. I'm concerned by what you have written.

My biggest concern is the fact that his nose is white. This can mean a severe anemia. If a cat is low on red blood cells it can cause the gums and the nose to look pale like this.

If I combine the symptoms of vomiting, lethargy and weight loss in an older cat there are a few things that can cause these symptoms.

My first concern is for kidney disease. When cats are quite far advanced into kidney disease then they can definitely be anemic.

Another possibility is hyperthyroidism. Hyperthyroidism can cause weight loss and vomiting, but usually cats with hyperthyroidism will still be eating. Is Stu still eating?

Unfortunately there are some cancers that can cause these symptoms as well.

Another thing that could cause these symptoms is a blood parasite called hemobartonella. This parasite is carried by fleas. However, this is not very common in older cats.

I would highly advise having some tests done on your cat. If this were my case I would definitely be recommending some blood tests which hopefully would tell us what is going on.

Some of these conditions are treatable, but I think when an older cat has these symptoms we have to be concerned.

Dr. Marie.

The color or type of vomit doesn't usually tell us too much (unless it is coffee grounds color in which case we are concerned about a stomach ulcer.) Foamy vomit doesn't really indicate anything.

I do believe that some cats will eat grass when they feel nauseous because they know that it will make them vomit and then hopefully they will feel better afterward. However, there are some cats who just like to eat grass!
