Our cat Boo boo is 13 years old. He's an oriental shorthair, which is basically a Siamese without the points. Boo traveled from Virginia to Maryland when I got him in 1997. Then in 2003 he traveled out to Hawaii. In 2007 we moved to Germany, exactly half way around the world from Hawaii. In 2009, we moved back to Hawaii. And Mr. Boo boo did all that with us. He's quite the world-traveled cat.
A few days ago, Mr Boo was diagnosed with hyperthyroidism. Fortunately, that condition is very treatable. I have medication that I put in his ear twice a day and he's doing well. He was vomiting a lot; sometimes 3-4 times a day and losing weight because he couldn't keep anything down. He hasn't vomited in two days, since the medication started, and he seems much more comfortable.
The vet said he's in very good shape and we should have him around for many more years.
