Can An Anti-anxiety Medication Help With Pet Allergies?

Hey this is very weird, but I started a medication called BuSpar two days ago, and ever since, the past two times that I have been around my boyfriend’s cat I haven’t had the itchy eyes, scratchy throat, and hives that I usually get. I always take benadryl around the cat, but they never really worked this well before. Can there be any connection? I tried to look this up on the internet but to no avail…thanks!
