four months ago i took my cat to the vet because he had lost a lot of weight and wouldn't eat , he had blood tests and urine tests.I was told he might have lung cancer. his appetite increased due to steroids and vitamin injections on a monthly basis.but no other signs are showing of any problems due to lung cancer he is eating well and functioning as a normal cat, other than he shakes his head a lot.any Ideas?
if you find a box of marlboro hidden under his bed, this is a bad sign
