My cat started acting strange a couple months ago, but the change was slow, and it took a while to notice, and when I did, my parents talked me out of taking him to the vet at first... eventually it got a lot worse and I took him in. He had lost half his weight since his last visit.
I was ready to do a lot to get him better, I was giving him tapazol for his thyroid, I was paying for his vet visits, I was going to start him on medicine for diabetes... but when he was at the vet getting ready to start treatment, they noticed he was worse than what they expected-- I okay'd a lot of stuff to try and help him, but the vet didn't know what to do..
