I guess the question is do you want a mild smell in your room of choice and a bad one on cleaning day (assumably outside), or with wire mesh I assume the smell would dissipate enough it wouldnt be as bad on cleaning day, but your room may smell a bit worse for it.
I ask because im going to be raising two-three colonies in a one-bedroom apartment in the next few weeks, and dont want guests to balk at the smell.
Any ideas besides treated bedding, good ventilation, vanilla in water, and ot overcrowding?
ASF's in small numbers don't smell so strongly your entire house will smell. I have a particularly sensitive nose to them too.
The hardware cloth is best for the animals health. Ammonia build up will make your rats sick. Rats have a higher rate of respiration than snakes, they also pee and poop a lot more too. More ventilation the better!
