i know this a very stupid idea but i checked with every possible airline that goes from us to canada and aside from frontier, who doesnt fly to canada, I'm out of luck. the guinea pigs would have to go in the cargo, unless i try to play them off as baby bunnies or cats. apparently most travel personnel dont give as much as a glance towards your animals, and most dont know what a guinea pig is and mistake it for a rabbit or cat. this is the last thing i can think of, if not I'm forced to put them in cargo and risk them even more. i just want some thoughts, opinions, similar experiences? the only thing that worried me is they find out they're not the animal i say it is and they take them away
