You're speaking with Dr. Michael Salkin. Welcome to JustAnswer. I'm currently typing up my reply. Please be patient. This may take a few minutes.

I can be more accurate for you if I can see what you're seeing. Can you tell me how he has responded to the steroid and antibiotics in the past?

Customer: replied 3 months ago.
I am not good at sending pictures
Expert:  Dr. Michael Salkin replied 3 months ago.

Thank you. Give me a moment to take a look, please...

Expert:  Dr. Michael Salkin replied 3 months ago.

Unfortunately, I can't make head nor tails out of that pic. I regret that if I can't see what you're seeing I won't be able to be as accurate for you as I would like to be. Perhaps you can get some help in taking a pic? If not, I'll opt out and you can contact customer service if you don't want to continue on in this conversation.

It is a large diameter hard dried raw spot about the size is the bottom of a cereal bowl
Expert:  Dr. Michael Salkin replied 3 months ago.

Thank you but the picture looks like a modern art painting to me. I can't make out one part of Shadow from another. I'll opt out which will allow another expert to take a look at these photos.

Here are better pictures

This is a picture of Shadow's mouth 4 months ago. But now it is all raw and red and a bigger area around his mouth
Expert:  Sarah Snow replied 3 months ago.


I am Dr. Snow, and I can try to help you with Shadow. That is indeed a hot spot, and the area on his mouth that is ulcerated is called a "rodent ulcer."
Both of these findings are consistent with an allergy. The problem is that it can be difficult to determine what Shadow is reacting to. Does Shadow go outside? Do you have any other pets?

How did Shadow do after the injections?

Customer: replied 3 months ago.
Shadow Is an only cat and is an indoor cat. Initially the steroid shot helped some what but the later ones did not
Expert:  Sarah Snow replied 3 months ago.

Ok, that is helpful to know. Here's what I usually suggest for these cats:

1. I like to use low doses of oral Prednisolone once the injection has had enough time to clear the system. I find it works better. This is a steroid, and I use it until we figure out the source of the problem.

2. Good quality flea prevention to rule out flea allergy - even if you're not seeing them!

3. Single protein food, preferably canned, but some cats will only eat dry. I like to stay away from fish and chicken. I really like the duck based diets for cats!

4. There are blood tests that can be done in cats to help determine environmental allergies, but they can be costly, and allergy injections sometimes help and sometimes don't.

5. Sometimes an antihistamine called Chlorpheniramine can help. You can get it over the counter at any pharmacy. In cats, we usually use 1/2 of a 4mg tablet twice daily.

6. Some of my clients find that using essential oils can help cats with allergic skin disease. There is a website called AnimalEO that makes one safe for cats called KittyBoost if you are interested.

Please post back with further questions!

Thank you. Do you think having him tested for allergies would be beneficial?
Customer: replied 3 months ago.
What helps rodent ulcer, does what you suggest work for both problems?
Expert:  Sarah Snow replied 3 months ago.

I think testing is beneficial, but I usually recommend ruling out flea allergy and food allergy first as they are easier to treat, and we don't want to miss them and then have to start over!

Allergy testing also gives an answer on what they may be allergic to, but then the goal is to provide a basis for formulating allergy injections, so I usually leave that as a last resort for that reason.

Steroids help the most for the initial treatment, in my opinion for both rodent ulcers and hot spots!

Customer: replied 3 months ago.
steroids will take care of flea and food allergies without being tested?
Expert:  Sarah Snow replied 3 months ago.

Steroids will generally treat any allergy. Blood testing will really only help identify environmental allergies, like dust mites, molds, pollens, etc. There is no good blood test for food allergies = food trials (trying new single protein food sources) are best for that. Using a good monthly flea prevention is the best test and treatment to rule out flea allergies.

Hope that makes sense!
