Yes, well thats just an approximate, although since its always being added onto its always growing, I should go through and count everything one of these days, just for the heck of it, and we just added on new snake racks that have 108 spaces in them..as for the rodents, most of the animals are on f/t, so we have a supplier for f/t rats and mice, and rabbits as well when we need them, we do however breed our own mice and rats, which we just set up a few months ago, its in one of the little shed/garages out back, 20x20..insulated and heater equipped, has to be for winter, plus hairless mice and rats are breeding out there as well, cant freeze them lol, my bf has constructed a few rat racks, and the mice are all in little lab trays. Overall I have to say it works out quite nicely, of course we are still getting more mice and rats out there to breed, but it takes awhile, we are probably going to have racks lined up against each wall, and possibly a row or two in the middle, but thats still just in the planning stage. I will see if I can get some pics of the rodent set ups, most likely after I change all the cages tomorrow out there. Looks like you have a nice rack you made. The mice are all on self drip watering systems, and some of the rats are as well that are in their own racks. Well thats about all I can think of on that subject at the moment.
