I hadnt heard from the vet, so just phoned her. Thyroid is within normal parameters, but he apparently has some renal dysfunction (didnt get the numbers on the phone, so not sure how bad it is) and there was blood in his urine. However, the renal dysfunction doesnt account for the fast breathing and lethargy - so now she wants to do an x-ray. Vet is still mentioning an allergy, asthma or - her words 'something more sinister'!!
by which I guess she's meaning heart? I dont' know - trouble is when I'm on the phone discussing this sort of thing, all the things I would normally want to ask, just seem to fly out the window - and as soon as I put the phone down I have a hundred and one questions going round in my brain! and now my vet isnt going to be around till Monday.
I really wanted it to be something relatively 'simple' like hyperthryoidism, I just want my Sammy to be back to normal and some definitive diagnosis - anyway, his x-ray is booked for next Wednesday.
