Q. Is there any information out there regarding a severe allergy to cat scratches? Is there any information out there regarding a severe allergy to cat scratches? I am not referring to "cat scratch fever" disease, but an allergy where the site of the scratch becomes swollen and red, and the person has hives and trouble breathing. Thanks so much!

A. Greetings Humble Earthling! It sounds like you have two or more things going on. First, cat scratch fever is caused by a parasite and comes on 1 to 2 weeks after the scratch. Allergic reactions are immediate.
Now, if the site of the scratch is swollen and red, that could be due to minor infection and just the process of healing.
