Pet's info: Cat | Domestic Longhair | Female | spayed | 17 years and 11 months old | 12 lbs
Hello, my Kitty was born in 2000. She has been very healthy her whole life. I've just noticed a bald patch on her front neck/chest area (she has long hair). For the past month or so, I've been giving her fancy feast gourmet cat food 3 oz. a day, in addition to her regular diet, Purina Cat Chow, Indoor + immune health blend. I added the fancy feast treat, because She's lost weight, not sure how much. I don't know what to do for her, please help? Thank you, Danette

Older cats like your kitty often get an overactive thyroid which will show weight loss, a really fast heart rate, sometimes vomiting, and more vocalisation than usual. Some cats get skittish as well. Hyperthyroidism can actually cause heart problems and mask kidney disease. Hyperthyroidism is easily diagnosed with a clinical exam and a little blood test and there are various treatments available, varying from Methimazole transdermal ointment or tablets to slow down thyroid hormone production, surgery to remove the overactive thyroid gland or radiotherapy. If your kitty is suffering from hyperthyroidism your vet will discuss the various options. I suggest you make an appointment tomorrow.
