I really want a pair of boys but I’m not sure if girls would be better. I heard boys can be extremely territorial and I’m not sure if being in a small travel cage for 5 hours every once in a while would cause them to fight over the small cage. Also this doesn’t exactly go under traveling but I’ve heard that boys smell REALLY bad, I’m not sure if it’s an exaggeration or not, what’s your experience? And one more thing- is it necessary to clean their sacs once a month? I would imagine most inexperienced people do not lmao. Is it difficult or smelly to clean? The smell issue here is more for the rest of my family than me. My 60 year old father lives with us and has a very sensitive sense of smell.
