Over-active thyroid ... causes high heart rate, weight loss, irritability and a host of other possible symptoms. Very common in older cats, like one of ours at the moment (which is how come I know about it!). He (the cat, not steve6) is on tablets for a month then an operation. A friend of mine has it too and is on tablets for life.
No doubt steve6's doctor will have requested a blood test for a definite diagnosis.
