You have 3 major approaches:
1. Treat conventionally – it is unlikely that they can help, and possibly will make her worse.
2. Try some self healing treatments listed below as these issues are not life threatening.
3. If that does not help, work with an integrative veterinarian. Even if these symptoms resolve, use one for the very best chance of health and long life and less money spent by you on your new puppy. Many homeopaths can consult with you by phone (like me) if there is now one near you.

If you were trained in different healing modalities you could help by using Reiki, T-Touch, HTA, flower essences, supplements, homeopathy and more.
1. Even before you are trained in Reiki, you can ask for this energy healing that cannot hurt and may help. this may decrease itching if that is causing the red skin and hair loss. It is excellent for any emotional problems (I can only assume the grunting may be emotional). It is also excellent to rebalance the immune system/energy field imbalance (possibly from the vaccines) which could help the grunting.
2. Mitomax is a super probiotic that can improve nutrient absorption, so helps with all problems. Unlike other probiotics, it is very stable and is ok at the low stomach pH.
3. Rescue remedy from the health food store. Put one drop in a separate water bowl. Put 10 drops in a cup of water and rinse red areas. Put 4 drops in an ounce of water in a jar and give a few drops in every meal and every few hours in between. You cannot use it too often. It is totally safe. It is great for people too – for anxiety, stress, shock, grief and more.
4. Skin Soothe for the red skin, and Vaccine Detox from Spirit Essences for the possible damage from the vaccines. Flower essences are totally safe and can be used as long and as frequently as they seem to help. Remember that using a journal will help you figure out what is helping the most. There are many other companies and combinations you could try.
5. Derma Strength from VetriScience is a nutritional supplement that can be used long term to generally support the skin.
6. Most importantly, change to a raw meaty bone diet as this cures, or at least helps, about 60% of dogs with skin and general health problems who come to my practice.

Do read the 7 Keys to Healthy Animals for other general health care.

Many conventional veterinarians do feel that dry food, even Science diet, causes bladder problems. The best diet for all cats is a raw meaty bone diet. Read more on this here.

Each cat may need different products to get them back into balance. First, how do you know she is out of balance at this point? Buying the Healthy Animal’s Journal here can help you do this evaluation.
1. Look at the early warning signs to see any she has.
2. Now that you have stopped the dry food, monitor her thirst and urine output. A healthy cat rarely drinks unless forced to by dry food.
3. Possibly contact an animal intuitive (I have list if you email me to see if there is an energy field out of balance.

If she has any symptoms, following the 7 keys to healthy animals is a great first step. Then you can no look at all the different holistic approaches available and pick one with which to begin. Maybe you will choose to work with a practitioner in your area, maybe you will consult by phone. Maybe one modality will have local classes you can take. Reiki, HTA, TTouch, Flower Essences, essential oils, herbs, nutriceuticals, homeopathy, chiropractic or chinese medicine are some of the approaches that can bring her back to balance.

I would start with Mitomax to maximize nutrient absorption from the gut.

Then I would select one of the totally safe flower essences – maybe UR fine from Spirit Essences . The site says it “balances the energy system and encourages proper flow of fluids.” Or UT Strength for Cats from Vetriscience - This maintains proper urinary tract function and supports the immune system.”

Then it depends on your cat and how she responds.
