She isn't hyperthyroid ATM but she is higher end of normal. Also her Chlorine slightly on the low side - he said the readings can change from day to day so he isn't too concerned. He said he wants to retest in a few months as due to her being high end of normal re thyroid, there is a chance the numbers could go higher. The good news is that her kidneys are fine so she can have Metacam if need be. I mentioned the infra-red bed and he is interested to know if it helps as obviously if it does, it has to be better than Metacam.
As for the Chlorine, I don't know what the implications are. if it gets any lower. I asked if diet could help but he said he wouldn't want to advise putting more salt in a cats diet - which makes sense. Hopefully the number will be higher the next time. So really her gastric issues aren't clear, although it is possible she strained from hacking up furballs. She had brought up 2 undigested Tesco own webbox sticks so maybe a piece had scratched her on the way up?
I am just cooking some coley so will offer her some of that
He said to worm again after giving her the rest of today to destress. She still hasn't eaten yet and AFAIK, not even had a drink which is worrying. It is high 20s here, although the lower ground floor is cooler, she has the heater on
