Hello. Stress can certainly affect a cats appetite, but if he has lost enough weight that it is now of concern to you, the best thing is to have your cat evaluated by a veterinarian. Your cat may just be adjusting to his new surroundings, or perhaps he is getting more exercise & just seems leaner, but if you are worried it is always best to have these things checked out as soon as possible.
