There is a new cat in the area and Sherlock doesn't like other cats, only see it once a day if that in the garden. Didn't feel any cuts or scratches. He hasn't vomited or coughed and has no medical conditions.
1- Any other symptoms2- Can you take a look at his gums and see if they are pink or pale?
3- Can you take his rectal temperature?
His gums are pink, don't have a themoneter
Friend, lethargy and decrease appetite are very non-specific symptoms and can be related to many different medical conditions that affect cats. Possible causes could be anemia, infections, ingestion of a foreign body, etc. to name a few causes. A very common cause in an indoor/outdoor cat is an infection or a fever. In this case, your cat will need a hands on examination, blood work (chemistry profile & CBC) and urinalysis as initial screening test to determine the exact underlying cause. Treatment will be based on clinical and diagnostic findings. In the meantime, offer him a bland diet of rice and boiled bonless chicken or ground beef; if possible blend the food and force feed him small amounts 4-6 times a day.
