<human>: Can you provide a brief rundown of the text in within 3 sentences?

My parents and a few of my friends have cats.  I like cats but by immune system doesn't.  As a result I get sniffly and watery eyes when I visit them and typically need to reduce my visit duration to keep myself from feeling terrible.  I've tried various different allergy meds to no success, other than benadryl but then I feel so effing tired.

So I thought maybe a respirator would help.  Would I need a full face respirator?  Seems like cat dander is an irritant to the eye as well as the lungs.  Anyone have any experience with using a respirator to limit allergic reactions?

On the same line, does any one else experience a "delayed reaction" to cat dander?  I was at my friend's last night but I didn't start sneezing up a storm until this morning.
<bot>: Aahchoo.  I'm thinking of buying a respirator to prevent cat allergies, wasn't sure if that would work and if I needed a half or full face mask.
