You can call the vet and get a pill for the itching, it is caused by allergy to flea bites, the pill cost around 15.00, I think and it lasts for a whole month, don't get the expensive pills and liquids that cost over 30.00. The vet has the other "pill" but it is not as expensive and I figure that is why they don't tell a lot of people about it, cause they want to sell the more expensive product. This is what we use on our furbaby. If we didn't he would chew all his fur off himself, also if you have a problem getting your pet to take the pill. Just crush it up and add a dropper full of water to it and dissolve as much as you can. Then, get the mixture back up in the dropper and put it in your pets mouth, if you need to you can add more water, a dropper full at a time.
