A. Changes in coat appearance can be caused by a number of things. In older cats, hair loss or changes in coat and skin confirmation may indicate a metabolic issue such as thyroid problems. Cats can begin to lose hair and may also show other changes such as weight changes or appetite changes. Blood work is usually done to check for this, and most pets do very well with a daily medication treatment.
Hair loss can also be caused by mites on the skin, external parasites or even skin and fungal infections. These may cause red bumps or sores to appear on the skin in addition to the hair loss and coat changes. Your vet can take a skin scraping of the area to check for mites and infections, and a preventive flea treatment can remove any external parasites. If an infection or mites are present, your vet can also prescribe an antibiotic or topical cream to treat.
After any treatment it may take a month or two for completely bald patches to grow back in. This is normal as the skin and follicles need some time to heal prior to beginning the hair growth cycle again.
