just 1 question you sterilize 64 tubs in less then half an hour and dry them hmm either you dont do it or your lieing about how long it takes to clean the tubs
1 simple reason you dont clean your tubs cages what ever properly infections and diseases break out
you say you can do it i say prove it lets see a vid of you pulling mice out of 64 tubs washing the tubs like should be done to properly clean them to keep with healthy standards dry them replace bedding and then mice i dont see it being done unless your jacked up on meth. my grandpa use to work at eastern Illinois collage had 75 mice cages the ones that dont need bedding as it dropped threw and 115 rat cages and i would go in on week-ends to help him clean them and it would take half a day so i been there done that cleaning the cages up to spec for safe living conditions for the mice and rats and it took longer then half an hour to do 64 cages.
i wouldn't of called you on this if you said an hour or 2 but less then half an hour come on lets see some proof
now i can see it done if all you do is dump the old bedding out and put new bedding in yes anybody can do that but to do it properly to not spread any diseases takes longer no ifs ands or buts about it
