Shortly after I took Lewis to the vet, I went out of town for 11 days. I did get an email from the vet saying that one of the blood tests came back okay, so that was good, but they were waiting for the other one. Then a week went by and I didn't hear from the vet, but to be honest with all the busyness and traveling I really didn't have time to think about it! So after getting home yesterday, I called the vet to ask if they got the results from the other test.
Basically, one of the tests was going to indicate some issues with the kidney. Those came back fine - he does have a *slight* elevation in levels, but that doesn't indicate kidney issues right now.
The other test was an ionized calcium test which is heightened calcium in his blood. That is usually caused by cancer. Lewis is only 4 1/2, and it's very rare to find cancer in a cat this young, though the vet has seen it before. Right now, there are two possibilities that we need to do further tests. One is that he has a thyroid tumor. We have to do a test for that specifically, and if it's the issue he'll need surgery. The other is that he has cancer or a tumor, and they want to do x-rays and scans on his body to see if they can find out where.
A third possibility is that it's purely behavioral. She asked if we had any major changes happen recently. I said things have been pretty normal around here except for the fact that I'm pregnant. I don't feel that I'm acting any differently, but I don't know what the cats can sense. The vet said that because his calcium levels are high, it probably is more than just a behavioral problem. I expressed concern about figuring out what's going on with Lewis earlier than later, because after the baby comes in September our whole house will be turned upsidedown.
I asked if we only did one, which one should we do, and the vet recommended the thyroid blood test. So I guess we'll have to make an appointment to get more bloodwork done, poor baby.
I need to add going to the vet to my to do list. It's getting long because I was gone for almost 2 weeks. :-) It'll have to go above "getting auto insurance quotes" and under "return books to library".
