Although cat allergy shots are only briefly touch on in this article, this is a wonderful article for explaining pet allergies themselves and how to lessen them for people who suffer from them. The article is easy to read and gives many helpful tips on how to cope with your pet allergies and still keep your pet. I like that it strongly suggests that if you have a pet allergy and don't currently have a pet please consider long and hard how your allergies would affect both you and your pet before you opt for one. There are 3 great downloadable tools on the page also.
