I live in Australia. I have been to see so many vets here including 3 cat specialists and ALL have different views. My cat's insulin doses are always high, always going up, up, up (7units, 7.5units, 8units) it never stops going up. Only 1 Vet suggested that my cat MIGHT have Acromegaly causing her insulin resistance. I dont really understand why cant my Vet cannot find out for sure whether my cat DOES or does NOT have Acromegaly? Surely there is a blood test for Acromealy as we live in the 21st Century.
