Hello and welcome. My name is Scott and I am an experienced small animal veterinary surgeon, I will be very pleased to work with you today and will try my best to answer your question to your satisfaction.
If your cat otherwise seems bright and healthy and is acting normally this is not likely to be any sort of health problem, just a curiosity.
It would be safe to cut this fur back now and again to improve his appearance but if any odd symptoms do occur then have your vet check him over just to be on the safe side.
That said I doubt if you have anything to worry about ...
The fur does hang from a flab of skin so this will be unable to cut fur cat is healthy does this apply to toms
Can you please reply to my question as regards cutting the fur as this is hanging from flabby skin??
Thank you for your help
