Poor Lilly! Flea allergy can be so stressful to deal with. The main thing is getting rid of fleas effectively as that is the inciting cause driving the itchiness resulting in scratching and self-traumatic lesions like that. If she is already on a flea preventative, then you could consider switching to a different product. There are many great product in the market such as Frontline and Bravecto, among others. Also, it is important to vacuum the house and all things that have contact with lilly frequently. Make sure the other kitties in the household are also on a flea preventative. Try this for 1-3 months and if does not make a difference, she may have another type of allergy such as a food allergy or environmental allergy. As for the wounds, try to keep the areas clean though if they are bleeding and infected, Lilly wound benefit from antibiotic therapy. Good luck and thanks for letting us take care of you today!
