first off, i wish you luck and success in your first year of breeding leopard geckos.
i would like to point out a couple of things for you to think about. yes, tremper is one of the pioneers and many of his husbandry techniques are now considered "standards" and the norm.
HOWEVER, think about this. how many leopard gecko breeders do u have???
compare that to mr. tremper. he has literally thousands...THOUSANDS. i would expect anyone with that many animals to test and experiment with the boundaries of any species for their own economical benefit. heck, for him the difference between not being able to house one extra gecko per cage can mean building an entire new complex the size of a safeway to house several hundred animals.
to be honest, i routinely house my breeders (1.3 to 1.5) in 32 qt boxes and i have been during so for the past several years. however, there are several things that i may do differently than other breeders (mainly the forementioned one) to make life "more comfortable" for my breeders. i always remove the male after i know he has successfully bred with all the females and they are gravid.
however, probably the most noticeable differences is that I CLEAN THE CAGES MORE OFTEN THAN HE DOES. i spot clean 2-3x a week and do an entire cage cleaning once every 7-10 days. now to some people, that may still not be frequent/clean enough but it is what works for me- all my geckos are housed in my bedroom/living room and i have no problems with any smell.
i do understand that tremper has several thousand animals and only a limited number of hours per day, but come on! hire some people if help is needed! letting fecal matter pile up in the cage like that is just straight digesting!
why do u think leopard geckos in the wild use a seperate area for their "bathroom purposes". because THEY ARE CLEAN ANIMALS. if they are willing to walk over to the next pile of rocks in the wild to do their thing, we should at least have the courtesy in the captivity to keep their cages somewhat clean! heck if we all were locked up in prison, we COULD live an okay life with our own fecal matter piled up next to us- but i'ld RATHER NOT!
yeah yeah, i've heard it all..."scent purposes" during the breeding season??? LOL, LOOK AT THE PICTURE!
that's probably the poorest excuse i have ever heard! so if feces increase "scenting", then leave a couple of pieces, nobody said to leave an entire three weeks worth! (that's how much it looks like to me in the picture). oh yeah, the water dish is placed off the ground "so that calcium powder won't get kicked in"? LOL you mean so that the water doesn't get contaminated by the leopard gecko shoulder-height pile of fecal matter!
okay that's enough, i'll stop now. you get my point. ALWAYS question anything that doesn't seem logical and do research. if your research has any doubts or doesn't seem right, then try it out yourself and learn from your own experiences.
i'll end my rabblings with a final word to sum everything up:
so sure, in my opinion 1.4 or 1.5 adult leopard geckos CAN be housed in a 32qt blanket box. but it doesn't mean they HAVE to be.
if u don't have hundreds or thousands of leopard geckos, then consider yourself as having a luxury. WHY? because u can spend MORE TIME, MORE EFFORT, and MORE SPACE to create a more spacious, spotless, clean environment for your animals!
peace
