Pet's info: Cat | Mixed Breed | Male | neutered | 17 years and 9 months old | 7 lbs

My cat has been loosing weight, vomiting his food/water occasionally for the past 6 months he's been having seizures for 3 yrs about once a yr. this morning he wasn't himself wouldn't eat and had puked in 8 small spot through the night and I noticed he's having balance issues in his back legs very miniscule and he's also twitching from very mild sounds like he's about to seize. Normaly he seizes with sounds like a loud ringer. Done blood work and everything checks out and I need a 2nd opinion.

Elvis' signs of weight loss, vomiting and seizure activity are highly concerning. I'm glad that his blood testing was normal, but in an older cat that is experiencing seizures, a brain tumor is a major concern and will not typically cause any changes on blood testing. An MRI scan is needed for this diagnosis. Normal blood work rules out common causes of weight loss in an older cat, such as kidney disease and hyperthyroidism, but as I mentioned, there is not a specific test for all cancers. Elvis needs to see his vet immediately because his twitching and balance issues could be a result of focal seizures rather than the grand mal seizures to which you are likely accustomed to seeing. Your vet will be able to discuss any recommended diagnostics and treatment options.
