A. You can try tempting to eat with some cooked chicken or white fish and serve it whilst it is still warm as it smells stronger and this can encourage eating. If this has been going on for several days or longer then you should see your vet and have some blood work done as it sounds like There is something going on inside. It could just be an infection that some antibiotics could sort out but it may also be something more sinister. The sooner you get Chuck seen the quicker you can start treatment.
