Thank you Sheila for that information.
There are a couple issues that would cause this hair loss:
Stress Induced Obsessive/Compulsive
For the allergic, this will respond to Benadryl at 1 mg per pound every 12 hrs. This is the infant liquid form at the pharmacy given with a dropper. If there is no response to this, have your vet examine Tammy to determine if there are parasites and/or infections that would require prescription medications. If Tammy is spayed, this could be due to the lack of hormones and your vet has treatments for this.
The last, stress induced OCD, may respond to Feliway. This is a feline pheromone that acts as a calming agent and will decrease anxiety.This can be purchased at the pet store.If this is not enough, your vet will have medications to help decrease anxiety and stop this skin condition.
In some older cats, they can have over active Sebaceous Glands that are oil glands within the hair follicles and when they over produce thsi oil, the fur will fall out. There is no treatment for this except weekly baths and brushing to remove the oils.
the best thing to do at home Sheila, is to purchase a daily supplement of Derm Caps or some form of Omega 3 fatty acids at the pet store. Apply an anti bacterial ointment to teh hair less areas every 12 hrs and see if she responds. If she does not, then diagnostics will have to be done to determine the cause and treatment.
Does that make sense to you. Sheila?
