This looks like it could be scabs and flea dirt. The blood in them is from bites usually. You can use a flea comb over her neck, back and tail and you will see live fleas and flea dirt in the comb if she has them. Dip the comb in soapy water to clean it and kill the fleas. If it's due to fleas you should treat your house and all the animals in the household. Make sure you use products that are safe for cats. Some cats get skin sores from grooming too much that causes hair loss and little scabs. That can be caused by stress. If they go away with antibacterial ointment they are from a skin infection. There are medications that can help this that you can get from your veterinarian. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Butters.

    This is probably caused by an allergic reaction. first of all make sure you flea Sunny regularly every month with a high quality spot on (ex. Advantage) as fleas are by far the most common reason for these reactions. If the fleas are not the problem, it could be an allergic reaction to food or an environmental factor. this is more complicated to treat and will sometimes require medications such as Steroids, anti histamines or cyclosporin in order to stop the allergy.
