Hi everyone I'm new here. My parents have a Persian that's around 15-16 yrs old. I found her on the street and has been living with my parents for 8 yrs. I've been trying to groom her over the yrs but in February I couldn't get a matt out so off to the groomer's. They shaved her pretty good and the hair hasn't grown back. She's been eating ok and her poops are normal. She's the sweetest thing. Something has to be wrong for the hair to stop growing, and since she's pretty old I don't think my parents will pay for a ton of tests, blood work, urine test etc to say there's nothing they can do cuz of her age. What's your opinion for this kitty. Thanks so much!!
