Our cat has been over grooming, originally I think it was flea allergy, but she is now flea free and still licking herself bald. 
She has been to the vet and had a hydrocortisone injection and I was looking at the feliway defusers as she is generally a jumpy sort of cat.
I am asthmatic though and react badly to glade plug ins, I know it's different, but has anyone any experience of using them with am asthmatic in the house?
