Welcome to JustAnswer! I am a licensed veterinarian and would be glad to help!
Is she an indoor only cat?
Do you notice, her licking or scratching at this area?
Is there weight loss?
She goes outside also in an enclosed space
I haven't noticed her scratching that spot
She seems to have lost some weight but not to extremes
Ok - thank you - I am going to list some thoughts to consider - please give me a few moments to be comprehensive in possible causes.
The most common causes for this, especially in a cat that can go outside (even for a brief period of time) include:1) Infectious causes:- Bacteria- Mites- Fleas2) Going back to the topic above - FLEAS and flea allergy dermatitis (not just the fleas themselves...) but the ALLERGY with cats associated with just one flea bite can be quite intense.3) There are some cats which will have fur loss due to internal reasons - and the most common one would be an overactive thyroid. For this reason, especially in older cats checking the thyroid value notably would be a consideration with your history.4) Environmental as well as food allergies can cause these signs as well, again - especially environmental even if going outside.For allergies, whether flea, food, or environment, options include:- Steroids (Prednisone - LINK HERE)- Antihistamines such as Benadryl (LINK HERE) or Loratidine (LINK HERE).IF diet is a concern - then a hypoallergenic diet example that is common to use in cats is Hill's Z/D (LINK HERE)Finally - there are some cats that have fur loss and there is just no cause we can identify....For these cats, it is thought that OCD/behavioral/anxiety related issues are the cause. (LINK HERE)For that as well, they can benefit from steroid injections - but owners also find it beneficial to consider a product called Feliway - LINK HERE or a calming collar (LINK HERE) which emits phermones/hormones that are supposed to decrease stress or anxiety in cats.
