I have my guinea pigs in an upstairs bedroom. They have had a morning in the run and I had just put them back. I heard this commotion upstairs and my neice had been spraying a load of hairspray in my piggies room. I have opened the window but is this going to be poisonous to my piggies. My neice is 10 years old so should know better. Please help. I'm really worried. 8...
