why does my cat constantly scratch?

I had a cat who would scratch around her neck because she was allergic to fiberfill stuffing used in some pillows and quilts. There's a cat sleeping pad that's actually made from uncovered fiberfill. It's marketing as collecting pet hair and dander. She used to have to get steroid shots and antibiotics because she would scratch until she created bloody, open sores.

Your cat might also be allergic to an ingredient in her food, or a detergent you use, or a cleaner that you use around the house. She probably doesn't have the tapeworm anymore. If she did, you would see little white segments in her stool. If you feed her dry food, you might try switching to feeding her just canned food, made with a high percentage of protein and no grains. Cats' digestive systems weren't meant to handle dry food with a high percentage of grain and animal by products. Many dry foods also contain all kinds of flavorings, coloring and other food additives that could cause an allergic reaction. I feed my cats food made by Go, BG (before grains), and By Nature.

You could try reducing her allergic reaction with a couple of therapeutic grade essential oil blends called ImmuPower and Peace and Calming. Just let her smell the oil from a distance or put a drop on your hands and rub your hands together and let her approach you. The oil blends will help balance her immune system and calm her body's reaction to allergens. You could also put Animal Scents ointment on her neck to soothe the skin and help it heal.

I would say it's from tapeworm, little rings form around the cats neck line, the rings that form there are normally itchy, and make cats irritated. The other suggestion is that your cat may be allergic to the food you are giving her. Take her to the vet and ask if that's a possibility.
