Has she had a fecal sample checked recently?
Has she been checked for blood parasites?

Hi,
Thanks for your reply. With your additional information there are a few more things that need to be ruled out. The first is hookworms. This is an intestinal parasite, and is easily overlooked. It probably isn't the culprit because they are way more common in kittens, but definitely needs to be checked. Here is a link to a page about hookworms:

The second thing is to look for blood parasites. Hemobartonella is the common name they used to be called. These will not show up on regular blood work. They are actually a mycoplasma and can be difficult to diagnose. There is a specific test called a PCR test that you will have to discuss with your veterinarian. Often if a blood parasite is suspected they are simply treated for rather than getting a definite diagnosis. The tetracycline antibiotics are effective against them. Doxycycline is commonly used in cats. Here is a link to a page about this problem with more details:

Another slight possibility is Ehrlichiosis, a tick borne disease. This is fairly rare in cats, and will usually cause additional symptoms besides anemia, but it wouldn't hurt to check. This requires a specific blood test to diagnose, and it is also treated with doxycycline.
If you have further questions let me know. If this answer is helpful please click accept. Thank you and best wishes for your kitty!
