Low blood cell count

I got a new kitten. My other two cats became sick shortly after i got her. symptoms: vomiting, drooling, sleepy, wont eat or drink. One got better with in few day the other one still sick. Iw rote it off as flue and didnt do much.

Took my healthy kitten to the vet to get her spayed and after he did blood work he found that her white blood cell count is very low ( 0.2). Now i am into a very pricy bill with all three cats.

 he thinks its panleukopenia or lukimea. both pretty much deadly.

I am devastated.

why is my kitten acting healthy if thats what it is? why did my other one get better?

could it be something else?

has anyone encountered anything like that?

Cats with FeLV can have the virus and seem normal. Did they all test positive for the virus? Didn't you have the kitten tested before bringing it into your family?   I am going to have someone who knows more about FeLV respond to you.  It may take a day or so.

Did the vet say anything about CaliciVirus? That virus produces a lot of the symptoms you are describing (mainly the drooling and lack of eating because of painful mouth ulcers). It can also show as a low white blood cell count. If you can open the sick cat's mouth. Is the tongue red and inflamed? Are the gums swollen with any white bumps? If so this is very likely what is going on. 

If it is Calici, it's entirely possible that the kitten would be recovering while the other is still sick. It is a virus and there is nothing you can do to "cure" it other than let it run it's course, though treating the symptoms is absolutely crucial. I'm wondering if the kitten was previously infected and recovering when you brought her home and now she has infected the other cat who is now at the peak of the virus. 

Regardless, I think you need another vet visit ASAP, and blood work does need to be done to rule out FeLV. The only reason I am not convinced it's FeLV is that the symptoms don't usually present so immediately. It takes a little while for the cat to become infected and start to show signs. And, even then, FeLV cats can still live many years. This sounds much more immediate- like you brought the kitten home and the other one became ill. 

If it is Calici then you need to start actively treating the symptoms. An antibiotic is usually prescribed to help with any secondary infections (that can be picked up while the immune system is compromised) but most importantly is SubQ fluids. You have to keep your cat hydrated to avoid kidney failure. On it's own Calici is not fatal. If a cat does die it is usually from the symptoms and from not eating and drinking. 

So, call the vet ASAP and ask them about Calici! Also keep in mind it is highly contagious so you need to quarantine the cat that is sick from the others to prevent re-infection. 

 I'm sending vibes that you can get to the bottom of what is going on and that all of your cats recover. Once you know what the problem is definitively start a new thread so that people can post more comments. Good luck! 

Glad you found us and a warm welcome. I am so sorry about your sick kitties. Yes, how very upsetting (and expensive) for you. Did the kitten ever get tested for FeLK/FIV? It could also very well be the Calici virus. Antibiotics won't really help with that virus but they will help with a secondary bacterial infection that could possible take over. Treating the symptoms will also help keep your kitties comfortable. It is kind of like the flu we get. Very contagious and has to just run it course. Did the vet give you any medications? I wish I had more to offer you other than just vibes and best wishes. I think your vet is your best bet right now and I would keep in contact via phone daily with any symptom changes.
