Aww poor Thomas! I agree that he looks quite thin. I think you should get him to a veterinarian very soon because it sounds like he make have an upper respiratory infection and need antibiotics. There are many other reasons for weight loss so a vet will also help you determine if it's just a respiratory infection or something more serious. You can try placing Thomas in the bathroom with the shower running because sometimes steam will help reduce mucous and open air says. However, I really think Thomas needs to see a veterinarian soon.
