I have a gorgeous Siamese boy cat whom I adore beyond reason. I took him in as a feral some six years ago and I reckon his age is 9 or 10. He has always been wonderfully healthy and has gradually overcome his shy, anxious nature to be loving and calm. Since we are new to this town, I have not yet found a veterinarian but think there is something going on with his health. In the past few days, he has become very lethargic and acts like he's stoned for lack of a better description. Is that worthing taking him to a vet for a potentially expensive workup? Or should I give it a few more days? What would you do if he was your cat? He goes outside but never leaves the yard and is still eating. I am worried...
