I have a complete set of USED Ancare laboratory rodent cages. Unlike cement mixing tubs, rodents can't get purchase to chew their way out of these. I used them for several years without a problem. Very easy to clean and change bedding.
7 guinea pig cages: 15"w X 22"L X 8.75"H
16 "single rat" cages: 8.5"L X 17"L X 8.5H
All cages come with laboratory water bottles too (dishwasher safe with rubber stoppers) granted the stoppers have been chewed on, but they still work. The picture gives you a good idea of the size comparison.
I would prefer local, as in Texas area trades.
Looking to trade for firearms, ammo, a plasma cutter, impact wrench, welding leathers, Lowes, TSC gift cards, etc. I'm a girl who likes her tools. Not limited to just these items either, who knows what else will strike my fancy. Worst I can say is "No thank you".
