This doesnt solve your problem however...i am severly allergic to guinea pigs...yes...not hamsters...not rodents at all..just guinea pigs..i got a guinea pig with a friend of mine and was holding it and i "felt" like i was so tired i just had to shut my eyes..you know when ur eyes wont stay open any longer...well my friend turned around and started yelling at me to hand her the guinea pig because apparently...my face swelled up..i got white dots all over my face my tears made burn streaks down my face and my throat started closing up..lovely..it was wonderful...but anyway back to what i was going to say..her grandmother rushed in to make a pot of coffee..im like oh thanks..im so important u gotta fill your coffee craving right now...but she came back and told me to drink the whole cup...and my throat definitely "widened?" ...i took benedryl and that coffee really helped me..so in emergencies drink coffee at least to get a head start on your throat closing if you get that system..if you cant drink coffee then well...im sorry and disregard my whole comment lol.
