We just returned from Spencer's ultrasound appointment. The vet said all his internal organs looked good with the exception of his liver being darker than normal. He said that can be seen in either hepatitis or lymphoma. He showed no signs of hepatitis on the blood tests. So, they did a biopsy of his liver to look for cancer cells. I should know something by late this week or next Monday at he latest. Spencer was not very cooperative at the vet, which I expected. He's such a nervous guy. They had to sedate him to do the tests & he's still woozy. I took the day off so I guess he'll be sleeping off the sedative & I'll catch up on some work. I'll let you know what the test results show.
