My cat has been lethargic, has some eye discharge, lost weight quickly, and only eats a little of his food. I dont know if this is due to old age (he is between 13 and 14), or if there is something very wrong. He also has been peeing on beds, which is very unusual, and seems to sometimes have a little bit of trouble walking. Pet's info: Cat | American Shorthair | Male | neutered

Poor Nelson! From your description, I would say that something is definitely wrong. 13 or 14 years is really not overly old for a cat, certainly not old enough to cause these symptoms due to "old age." Some common causes of weight loss, decreased appetite, and acting lethargic along with peeing in odd places and difficulty walking would include diabetes, hyperthyroidism, or chronic kidney disease. I would recommend having Nelson examined by a vet as soon as you are able to - he/she can do basic blood work and a urinalysis to check for these problems and help determine what is causing his symptoms. In many cases, these illnesses are quite treatable once a diagnosis is made, so there's a good chance that your vet will be able to help.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Billu! I am concerned that Billu may have something metabolic going on that is causing him to not eat and lose weight. There are metabolic conditions that cause a cat o drink and urinate more. I recommend taking him to the Vet for an exam and blood work. A lot of the conditions that cause his symptoms can be diagnosed on blood work and urine. Possible causes are: kidney failure, diabetes, liver disease, increased calcium, cancer, intestinal disease (inflammatory bowel disease), urinary tract infection, bladder stones, crystals in the urine. I recommend ruling out medical causes before assuming his inappropriate urination is behavioral. I hope this helps and I wish you and Billu the best!
