We bought 2 guinea pigs 7 days before our 7 yr old began coughing and running a constant low grade temp. WE're now on day 13, but have taken 5 days of z-pac, xopenex nebulizer and codituss cough med with codiene. Her coughing during the day is much improved but as soon as she lies down for bedtime the coughing begins. She coughed over an hour before falling asleep and then coughed almost non-stop from 1:30-6:30 this am. Still running a low-grade temp. No wheezing but is this asthma, allergy, virus? Are the guinea pigs causing all of this? In need of a good night's sleep, mommy
