Why is my 18-year-old cat underweight with matted fur and dry scabs?

Updated On September 23rd, 2025

My father has a DSH cat who is roughly 18years old. She has been having some problems when it comes to fur/ skin. He hair will mat and fall out extremely easily and she has quite a few scabs down her spine and beside the spine which don't look infected they just look dry. I'm wondering if this is caused by maybe the fact that she struggles to groom herself or that she has hypothyroidism. She is quite under weight as she struggle to put and keep on weight. Thanks Niki

Hi Niki. 18 is a great old age for a cat but it is likely that she is starting to have some age related illnesses. Older cats may be prone to hyperthyroid which can make them lose weight, have skin issues and other problems. Renal (kidney) disease can also affect our older kitties. I would suggest that your dad's kitty see a veterinarian for a senior checkup and some bloodwork. Many of these conditions can be diagnosed on a bloodwork screen and there are multiple medical options to treat to give her the best quality of life in her golden years.
