tried various tubs varying degrees of thickness . Unfortunately I must have got '' The Demon Chewers from Hell '' .this , even more unfortunately for myself and my enduring wife , turned out to be a genetic trait , passed on to ALL the young.

Even reinforcing the vent holes with STEEL washers was to no avail .

I eventually ( why I did not sooner I will never know , ok ahm a guy , a stubburn dude ) switched them all over to glass tanks .

There is nothing more satisfying to someone who spent an entire weekend catching escapes , than watching the little varmits ( sp?) SLIDING down a glass wall with a look of utter disbelief on its face . Life is good , now !
