A few weeks ago my cat developed a cough, we took him to the vets who took some tests and prescribed antibiotics and steroids, this cleared his cough but it came back a few weeks later. He was then given more antibiotics and his cough has cleared up but the vet said the tests have revealed he has aggressive cancer in both lungs and will need to be pts. He is still eating and drinking, still chasing around and still acting his normal self, he is still happy.
I don't know what to do, obviously I don't want him to suffer but while he still seems well I don't want to have him puts for no reason. I am aware cats can hide their symptoms but could the vet be wrong?
My cat is almost 14 yrs old and I have his two litter siblings also.
What should I do?
