My cat is losing hair in one spot on his back. Why is this happening?
Hello, sorry to hear about Levon. This non-specific hair loss could be associated with different conditions. Most commonly, contact allergies from environmental allergies (dust mites, skin dander, detergents, grasses, heat) may cause this. Other causes could include anxiety and excessive grooming. External parasites or skin infections that could also cause constant itching, and finally, any metabolic endocrine diseases (diabetes and hyperthyroidism) may cause this. Less likely a hair disorder like becoming bald but he should not have had hair re-growth after his first incident.
Oral supplements like essential fatty oils will help keep his hair shiny but may not promote his hair growth. If his hair loss progresses or continues, then he should be seen by his veterinarian to further discern between the different causes of hair loss.
Hope this helps and best of luck.
