Dutchess. Cat. 14yo. No previous vet care but also no previous problems. Now is losing hair and weight- about a month or so. She is pooping in litter box and not covering it up. Also peeing in house more than usual. (She always marked occasionally now she is just urinating in every- not the marking smell but regular pee). She is still very happy and lovey and eating good. she is 7 pounds and last year was like 11 or 12. Thank you for your help!

Duchess needs to visit her veterinarian. Changes in her coat can indicate many things including thyroid disease, stress or allergies. The weight loss is most concerning for a many conditions including thyroid disease, kidney disease, cancer or diabetes. Changes in her litter box behavior could also be explained by any of the above listed health conditions. Best to play it safe and have her examined by the veterinarian. They will check her blood and urine for any abnormalities and this will give you a better idea of the cause and treatment. Best of luck.
