This article doesn't talk about cat allergy shot, but about all the other options in treatments that you have available for dealing with your allergies. The article is comprehensive and I thought the videos were excellent in adding details. I learned that my son is using his MDI wrong, so this article was extra helpful for me. The questions for your doctor at the end of the article were an added bonus. There are also helpful links at the bottom of the pages and one of them is about allergy shots.
