I'm sorry to hear this Amy, but try not to get too worried. There are a VAST number of things that can cause elevated white counts, from scary things (which I seriously doubt) to something as simple as a UTI, and even sometimes high stress level can elevate it. It somewhat depends on how elevated, but if it was something shockingly high I imagine your vet would be doing more testing and worrying about it. Please try not to worry. Look at it as a headache if you can. You can look up headaches and find some seriously scary things that cause them, but more than likely it is nothing like that and most headaches are minor and temporary without devastating cause.

You and Keva will be in my thoughts. I'm glad to hear she is acting well. That's a prime indication that she's doing just fine! Give her and Nebo some hugs and kisses for me
